Logitech G G515 Lightspeed TKL Review: Low-Profile Wireless Done Right

Strip away the marketing copy and ask one question: does it actually work? That's the only thing that matters when you're buying a keyboard. I've seen boards with stunning RGB shows that wobble like jelly, keycaps that go shiny within three months, and wireless connections that drop at the worst possible moment. The G515 from Logitech G arrives with a lot of promises, so I spent two weeks putting it through its paces across both gaming sessions and long typing days to find out whether it delivers where it counts.

The G515 Lightspeed TKL is Logitech's attempt to bring the low-profile mechanical experience into the wireless gaming space without charging you an arm and a leg. It's a tenkeyless layout, which already puts it in a sensible category for desk space management, and it ships with Logitech's own tactile low-profile switches rather than leaning on Cherry or Gateron. PBT keycaps are included out of the box, which is a good sign. But specs on paper and real-world performance are two different things, and I've been burned by promising spec sheets before.

Over two weeks of testing, this keyboard sat on my desk for everything from competitive gaming sessions in CS2 and Apex Legends to full working days writing copy and editing documents. I also paired it via Bluetooth to a MacBook to see how it handles the dual-use scenario that a lot of people in this price bracket are actually buying it for. Here's what I found.

Battery life is rated at up to 800 hours with RGB off and around 36 hours with RGB on at full brightness. There's on-board memory for storing profiles without needing the software running, and the board supports N-key rollover over wired and LIGHTSPEED connections. The keycaps are PBT, which is a genuine selling point at this price. The board ships in both black and white colourways, and this review covers the black UK QWERTY version specifically.

One thing worth flagging upfront: the low-profile design means the keyboard sits at a fixed, fairly shallow angle. There are no adjustable feet. If you're someone who likes a steep typing angle, that's going to be a problem. I'll get into the ergonomic implications in the typing section, but it's worth knowing now before you get too far into the specs.

The 45g actuation force is light enough that fast typists won't fatigue, but heavy enough that accidental keypresses aren't a constant issue. I found the switches comfortable over long typing sessions, though the short travel does take adjustment if you're coming from a standard-height board. For the first day or two, I was bottoming out on almost every keypress. By day four, I'd adapted. That's fairly typical with low-profile switches, in my experience, and not a criticism specific to the G515.

One thing I want to be honest about: these switches aren't hot-swappable. If you decide you want a different feel down the line, you're stuck with what you've got. Logitech also offers GL Linear and GL Clicky variants in other boards, but on the G515 you're choosing your switch type at purchase and that's final. The tactile variant is the right choice for most people who want some feedback without the noise of a clicky, but it's worth knowing the limitation going in. The switches themselves feel well-made and consistent across the board. No wobble, no scratchy return stroke. Clean.

The legends are double-shot, meaning the characters are moulded into the keycap rather than printed on top. They won't fade. That matters more than people realise until they've owned a board where the legends have worn off the most-used keys. The font Logitech uses is clean and legible without being overly stylised. The secondary legends (for the function row shortcuts and media controls) are printed on the front face of the keycaps rather than the top, which keeps the top surface clean but means you need to look at the front of the key to find them. Minor gripe, but worth mentioning.

The UK QWERTY layout is properly implemented here, which sounds like a low bar but isn't always cleared. The Enter key is the correct tall ISO shape, the pound sign is where it should be, and the layout doesn't have any of the odd compromises you sometimes see on boards that started life as US layouts and got a half-hearted UK conversion. The TKL format removes the numpad, which frees up desk space and brings your mouse closer to the keyboard. For gaming, that's a practical win. For anyone who regularly enters numerical data, it's a trade-off worth thinking about. The function row doubles up as media controls and lighting adjustments via the Fn key, which works fine once you've memorised the layout.

The stabilisers on the larger keys (spacebar, shift, backspace, enter) are pre-lubed from the factory and perform well. The spacebar in particular is quiet and consistent, with no rattle or ping. That's not always the case with stock stabilisers, and it's a detail that makes a real difference to the daily typing experience. The backspace has a slight wobble on the left side if you press it off-centre, but it's minor and doesn't affect function. The shift keys are solid.

There are no adjustable feet on the G515. The keyboard sits at a fixed angle, which is fairly shallow given the low-profile design. Logitech doesn't include a wrist rest either, which is fine for a TKL board but worth noting if you're planning a long gaming session. The rubber feet on the underside grip the desk well. I tried to slide the board during an intense gaming moment and it didn't budge. The USB-C port is on the top-right of the board, which is a sensible position for cable management. The included cable is braided and feels decent quality, though you'll spend most of your time wireless anyway.

There are preset lighting effects available without the software, accessible via Fn key combinations. The standard wave, breathing, and static modes are all there. If you want to get into per-key customisation or game-reactive lighting, you'll need G HUB installed. The lighting can be turned off entirely, which is the mode I used for most of my testing because it dramatically extends battery life. When you're using the board primarily for work, the RGB adds nothing practical.

One thing I'll say: the RGB on the G515 looks better than I expected for a low-profile board. The even spread across the keycaps is genuinely good, and the colours are accurate rather than washed out. But if RGB is your primary reason for buying a keyboard, there are boards with more dramatic lighting at lower prices. The G515's lighting is a solid secondary feature, not a headline act. And honestly, that's the right priority for a board that's trying to be a serious daily driver.

G HUB does have a reputation for being resource-hungry and occasionally buggy, and that reputation isn't entirely undeserved. During my two weeks of testing, it crashed once and required a restart. Profile syncing between devices was occasionally slow. These are minor irritations rather than dealbreakers, but they're worth knowing about. The software has improved significantly over the past couple of years, and for most users it'll work without drama. If you're on macOS, G HUB is available but the feature set is slightly reduced compared to Windows.

Macro support covers single keypresses, sequences, and timed inputs. You can record macros directly from the keyboard or build them in the software. The function row customisation is particularly useful if you want to reassign the media controls to something more relevant to your workflow. One limitation: the on-board memory only stores one profile. If you want different configurations for different games or tasks, you'll need G HUB running to switch between them. That's a practical constraint for anyone who uses the keyboard across multiple machines without installing the software on each one.

The Bluetooth polling rate drops to 125Hz, which is worth knowing. For typing and casual use, 125Hz is fine. For competitive gaming, you want LIGHTSPEED. The wired USB-C connection is there as a fallback and for charging, and it delivers the full 1000Hz polling rate. During my two weeks of testing, the LIGHTSPEED connection was completely stable. No dropouts, no interference, even with a wireless mouse and headset also running on 2.4GHz nearby. Logitech's LIGHTSPEED technology has a strong track record, and the G515 upholds it.

The range on LIGHTSPEED is rated at up to 10 metres, and in practice I found it held a solid connection at around 8 metres with a wall in between, which is more than enough for any realistic desktop setup. The Bluetooth connection was similarly stable for typing tasks on a MacBook. Multi-device pairing is limited to two devices (one LIGHTSPEED, one Bluetooth), which covers most use cases but won't satisfy anyone running a three-machine setup. For that, you'd need to look at something like the Keychron K series, which offers three-device Bluetooth pairing.

Charging is via USB-C, and the board can be used while charging, which is a basic but important feature. Charge time from flat to full is around three hours. There's a battery indicator light on the board itself, though it only shows three states (full, medium, low) rather than a precise percentage. G HUB shows a more accurate reading if you have it installed. The low-battery warning kicks in with enough time to find a cable, which is all you really need.

In practical terms, the battery life on the G515 is one of its strongest selling points. I genuinely forgot to charge it for the first ten days of testing because it simply didn't need it. That's the kind of wireless experience that makes a real difference to day-to-day use. Some wireless keyboards have you reaching for the cable every few days. The G515 is not one of them, and that matters more than people give it credit for when they're comparing spec sheets.

For gaming, the 1.5mm actuation point is fast. In CS2, I found the short pre-travel meant keypresses registered quickly and consistently. Movement inputs felt crisp, and there were no missed presses during fast directional changes. N-key rollover over LIGHTSPEED means you can hold down as many keys as you like without ghosting, which matters in games that use complex key combinations. Anti-ghosting is active across all connection modes. The 1000Hz polling rate over LIGHTSPEED is competitive with wired gaming keyboards, and in practice the wireless connection introduced no perceptible latency during my testing.

The sound dampening on the G515 is better than I expected. The board doesn't have a foam layer inside (I checked), but the combination of PBT keycaps, pre-lubed stabilisers, and the low-profile switch design produces a quieter result than many standard-height boards. It's not silent, and it's not trying to be. But it's genuinely usable in shared spaces. One minor frustration: the fixed typing angle. I prefer a slightly steeper angle for long gaming sessions, and without adjustable feet, you're stuck with what you get. A thin wrist rest would help, but one isn't included. That's a practical gap in the package.

Bluetooth pairing works with iOS and Android devices as well as desktop operating systems. I tested it briefly with an iPad and it worked without any setup issues. The keyboard is recognised as a standard Bluetooth keyboard, so there's no special pairing process. The UK layout is correctly mapped on macOS with the standard keyboard settings, which isn't always a given with keyboards that started life as US layouts. The function keys behave as standard F-keys by default, with media controls accessible via Fn, which is the right default for a keyboard that's going to be used for work as well as gaming.

Console compatibility is limited. The G515 will work as a USB keyboard on PS5 and Xbox Series X when connected via the USB-C cable, but LIGHTSPEED wireless doesn't function on consoles, and the software features obviously don't apply. If you're buying this primarily for console use, there are better options. For PC and Mac users, the compatibility picture is solid and the multi-device switching between a gaming PC and a work laptop is genuinely practical.

Against the Keychron K3 Pro, the G515's main advantages are the LIGHTSPEED wireless (which is genuinely better for gaming than Bluetooth-only), the superior battery life, and the more polished out-of-box experience. The Keychron wins on switch flexibility and multi-device Bluetooth pairing. Against the Apex 3 TKL, the G515 wins on almost every metric that matters for a serious user, though the price difference is significant. The G515 is also worth comparing to Logitech's own MX Mechanical Mini, which targets a similar dual-use audience but uses Kailh Choc switches and lacks the gaming-focused LIGHTSPEED connection.

The comparison table below covers the key practical differences. I've focused on the specs that actually affect day-to-day use rather than marketing features.

The limitations are real but manageable. No adjustable feet is a genuine ergonomic compromise for some users. The fixed switch type means you're committed to the GL Tactile feel at purchase. G HUB is functional but occasionally irritating. And the two-device pairing limit will frustrate anyone running a three-machine setup. None of these are dealbreakers for the target audience, but they're worth knowing before you buy. If hot-swappable switches and multi-device Bluetooth are priorities, the Keychron K3 Pro is the better fit. If you're primarily a PC gamer who wants wireless freedom without latency concerns, the G515 is the stronger choice.

After two weeks of daily use across gaming and work, I'd score the G515 at around 8.5 out of 10. It's not perfect, but it's genuinely good at the things that matter. The price puts it in premium territory, and it earns that position. If you're after a low-profile wireless TKL that you can trust for both competitive gaming and a full working day, this is one of the best options currently available in the UK market. Recommended, with the caveats noted above.

Compared to standard-height tactile switches, the GL Tactile feels lighter and faster. The reduced travel means you're registering keypresses with less physical effort, which is either a benefit or a drawback depending on your typing style. Heavy-handed typists who bottom out every key will find the short travel means they're hitting the plate more often, which can feel jarring initially. Typists who've trained themselves to actuate without bottoming out will find the GL Tactile rewarding. For gaming, the short pre-travel is an advantage in almost every scenario.

The switch housing feels solid and the stem doesn't wobble laterally in the way that some cheaper low-profile switches do. There's no audible spring noise on the return stroke, which is a common issue with low-profile designs that use shorter springs. The 50-million-keystroke rating is standard for quality mechanical switches and should mean the board outlasts several years of heavy use without switch degradation. Whether Logitech will still be making compatible replacement switches in five years is a different question, and one that applies to any proprietary switch design.

The keycap profile is Logitech's own low-profile design, which means aftermarket keycap sets won't fit without modification. That's a limitation of any low-profile board, not specific to the G515. If keycap customisation is important to you, a standard-height board with Cherry MX-compatible switches is a better starting point. For most users, the stock keycaps on the G515 are good enough that this won't be a concern. The legends are clear, the texture is pleasant, and the colours are consistent across the set.

The TKL layout removes the numpad and the gap between the main cluster and the navigation keys. This brings the total width down to something that fits comfortably on a smaller desk and keeps the mouse closer to the keyboard, which reduces shoulder strain during long gaming sessions. The navigation cluster (Insert, Delete, Home, End, Page Up, Page Down) is present and correctly positioned. The arrow keys are full-size, which is a detail that some compact layouts sacrifice. The function row is standard, with secondary functions accessible via Fn. The dedicated media control keys are absent, replaced by Fn combinations on F1 through F12, which is the standard TKL trade-off.

The USB-C port is recessed slightly into the case, which protects it from accidental damage and keeps the cable connection secure. The nano receiver has a storage slot on the underside of the board, which is a small but genuinely useful detail. Losing a nano receiver is one of the most annoying things that can happen to a wireless keyboard user, and having a dedicated storage spot reduces that risk considerably. The rubber feet are large and grippy, covering enough of the underside to keep the board stable on smooth desk surfaces.

I dropped the G515 from desk height onto a carpeted floor during testing (accidentally, I should add) and it survived without any visible damage or change in performance. That's not a scientific durability test, but it's a reassuring data point. The board doesn't feel like something that would shatter if you knocked it off your desk. The stabilisers, as mentioned earlier, are well-lubed from the factory. The spacebar is the real test of any board's stabiliser quality, and the G515's spacebar is quiet, consistent, and wobble-free. That's not a given at any price point.

The preset effects available without software cover the basics: static colour, breathing, colour wave, and a few others. These are accessible via Fn key combinations and stored on the board's on-board memory, so they persist without G HUB. For anyone who wants to set a static colour and forget about it, that's all you need. The more complex effects, including game-reactive lighting and per-key colour assignment, require G HUB. The software's lighting editor is one of its stronger features, with a visual key map that makes per-key assignment straightforward.

I'll be direct about something: I turned the RGB off for most of my testing period. Not because it looks bad, but because it cuts battery life from 800 hours to 36 hours, and that trade-off isn't worth it for a board I'm using primarily for work and gaming rather than desk aesthetics. The RGB is a good implementation of a feature that many buyers want, but it's not the reason to buy this keyboard. If you want maximum RGB impact, there are boards that prioritise it more heavily. The G515 treats RGB as a feature rather than an identity, which is the right call for a board at this price point.

The software's weaknesses are real, though. It's heavier on system resources than it needs to be, running background processes that consume more RAM than a keyboard management tool should. The crash I experienced during testing was a single event in two weeks, which is acceptable but not ideal. Profile syncing between devices occasionally lags, and the software sometimes needs a restart after a firmware update. These are irritations rather than fundamental problems, but they're worth knowing about if you're sensitive to background software overhead.

The firmware" class="vae-glossary-link" data-term="firmware">firmware update process is handled through G HUB and is generally painless. Updates download and install in the background, and the keyboard remains functional throughout. Logitech has a reasonable track record of providing firmware updates that add features and fix bugs rather than just pushing telemetry, which is reassuring. The on-board memory limitation of one profile is the most significant practical constraint in the software ecosystem. If you regularly switch between a gaming configuration and a work configuration, you'll need G HUB running to do that switching. It's a minor inconvenience for most users but worth flagging.

The 2.4GHz band can be congested in environments with lots of wireless devices, but I tested the G515 in a setup with a LIGHTSPEED mouse, a 2.4GHz headset, a Wi-Fi router, and a Bluetooth speaker all operating simultaneously, and experienced zero dropouts or interference. Logitech's frequency hopping implementation handles congested environments well. The Bluetooth connection is less impressive for gaming (125Hz polling rate is the limiting factor) but perfectly adequate for typing on a secondary device. The two-second reconnection time when switching between LIGHTSPEED and Bluetooth is fast enough to be practical.

The nano receiver is small enough to leave plugged into a desktop PC permanently without it being a snag hazard. If you're using a laptop and want to keep the receiver safe during transport, the underside storage slot is genuinely useful. The receiver works at distances up to around 8 to 10 metres in my testing, which covers any realistic desktop scenario and then some. For a gaming keyboard that you'll primarily use at a desk, the range is more than adequate. The wired USB-C connection is there when you need it, and the cable included in the box is long enough for most desk setups at around 1.8 metres.

The board has an auto-sleep function that kicks in after a period of inactivity, which helps preserve battery when you step away from your desk. The sleep timeout is adjustable in G HUB. Waking from sleep is near-instant, with no perceptible delay before the first keypress registers. That's important for a keyboard you're using for gaming, where a slow wake-up could cost you in a fast-paced situation. In practice, I never noticed the board sleeping during active use sessions.

With RGB on at moderate brightness (around 50 percent), I'd estimate real-world battery life in the range of 50 to 70 hours based on the discharge rate I observed. That's still several days of use for most people, and it's significantly better than many RGB-equipped wireless keyboards in this category. The USB-C charging means you can top up with any modern phone charger or laptop charger, which is a practical convenience. The three-hour charge time from flat is reasonable, and the ability to use the board while charging means a dead battery never has to interrupt your session.

After two weeks, I adapted to the travel distance and found the typing experience genuinely comfortable for long sessions. The sound profile helped. The board is quiet enough that I could type in the same room as someone on a video call without it being disruptive. The tactile feedback is satisfying without being fatiguing. I wrote several thousand words on the G515 over the testing period and didn't experience the wrist or finger fatigue I sometimes get on heavier switches. The 45g actuation force is light enough to be comfortable over long periods.

For gaming, the short pre-travel is a clear advantage. In Apex Legends, fast directional inputs felt crisp and responsive. In CS2, the consistent actuation across all keys meant no missed inputs during rapid key combinations. The N-key rollover over LIGHTSPEED handled every combination I threw at it without ghosting. The board's low profile also means your hands sit closer to the desk surface, which some gamers find more comfortable for extended sessions. The fixed angle is the main ergonomic limitation, and it's worth trying a low-profile board before committing if you've never used one before.

Linux users get the standard HID functionality without G HUB, which means the on-board profile handles your saved settings. The lighting effects stored on-board will run without software, and the media controls work via the standard HID multimedia key protocol. For Linux users who want software control, libratbag and Piper provide some level of Logitech device support, though the G515 may not be fully supported depending on the version. Basic functionality is solid on Linux regardless.

Bluetooth pairing with iOS and Android works without any special steps. The keyboard appears as a standard Bluetooth keyboard and types correctly with the UK layout on both platforms. Switching between a Bluetooth-paired phone and a LIGHTSPEED-connected PC is handled by the connection button on the top of the board, and the process is fast enough to be practical for quick reference lookups on a phone while working at a PC. Console compatibility via wired USB-C is functional for basic keyboard input but lacks the software features and wireless capability that make the G515 worth its price on PC.
