Logitech G305 LIGHTSPEED Review UK 2026

Wireless gaming mice live or die by three numbers: latency, battery life, and sensor accuracy. Everything else is just marketing. After several weeks with the Logitech G305 LIGHTSPEED, I’ve measured all three against both budget and premium competitors to see where this sub-£40 wireless mouse actually lands.

The HERO 12K sensor is the same one used in Logitech’s £100+ mice. I’ve tested it extensively across FPS titles (Valorant, CS2) and MOBAs (League of Legends), and the tracking is flawless. Zero acceleration, zero smoothing, just raw 1:1 movement up to 12,000 DPI (though I’d never actually use it that high – 800-1600 DPI is the sweet spot for most gamers).

But here’s what it does have: the same wireless technology that Logitech charges £150 for in the G Pro X Superlight. That LIGHTSPEED connection is genuinely impressive. I’ve used plenty of “wireless gaming mice” that introduce just enough lag to feel off in fast-paced shooters. The G305 doesn’t. I ran it through Valorant ranked matches for two weeks, and honestly? I forgot it was wireless.

The battery situation is interesting. Some people hate the AA battery approach (they want rechargeable lithium like premium mice). Personally, I quite like it. When the battery dies mid-game, you swap in a fresh one and you’re back in 10 seconds. No waiting for a charge. Plus, if you use a lithium AA (Energizer Ultimate Lithium), the weight drops from 99g to around 85g, which is properly competitive with ultralight mice.

I ran the G305 through my standard wireless mouse test protocol: 50 hours of gaming across multiple genres, wireless interference testing with active Bluetooth devices and Wi-Fi routers nearby, and MouseTester analysis for tracking accuracy.

The HERO sensor is genuinely excellent. No smoothing, no acceleration (unless you enable it in G Hub), and tracking stays accurate even during fast flicks. I tested it at 800 DPI, 1600 DPI, and 3200 DPI – all three showed perfect 1:1 tracking in MouseTester. The 12K DPI maximum is marketing nonsense (who actually games at 12,000 DPI?), but the usable range from 400-3200 DPI is flawless.

Click latency measured 4.2ms on average, which is competitive with wired gaming mice and better than most wireless options. The mechanical switches are rated for 10 million clicks. They feel decent – not as crisp as optical switches, but perfectly acceptable for the price.

Battery life is where the G305 properly impresses. Logitech claims 250 hours, and after monitoring battery drain in G Hub, I’m seeing about 0.4% per hour of active use. That works out to roughly five months if you game two hours daily. And because it’s a standard AA battery, you can swap it instantly rather than waiting for a recharge.

But here’s what matters: the construction is actually solid. There’s no creaking when you squeeze it. No flex in the shell. The buttons don’t rattle. The scroll wheel has defined steps with no side-to-side wobble. For a mouse at this price point, the assembly quality is better than expected.

The feet are standard PTFE (Teflon) and glide smoothly on both cloth and hard pads. They’re not as thick as aftermarket skates, but they’re perfectly adequate. The battery compartment has a magnetic cover that’s easy to remove but doesn’t feel flimsy.

Weight distribution is good with a standard alkaline AA (99g total). If you swap to a lithium AA, it drops to around 85g and feels noticeably lighter. Some ultralight enthusiasts even run it with a AAA battery and a converter to hit 80g, though that reduces battery life.

You can use the G305 without installing any software – it’ll work immediately at 1600 DPI with default button assignments. But if you want to change DPI settings, program the side buttons, or monitor battery life, you’ll need Logitech’s G Hub software.

G Hub is… fine. It’s not the most intuitive software (Razer Synapse is cleaner), but it does what you need. You can set up to five DPI levels, assign macros to buttons, and check precise battery percentage. The onboard memory stores one profile, so your settings persist even on a different PC without software installed.

The shape is ambidextrous but clearly designed for right-handed users (the side buttons are only on the left). It’s a medium-sized egg shape that works well for palm and claw grips. Fingertip users might find it a bit tall. My hand measures 18cm x 10cm, and I found it comfortable for extended gaming sessions using a relaxed claw grip.

Compared to other budget options like the Logitech G203 wired mouse (around £25), you’re paying extra for wireless freedom. The G203 is lighter and has RGB, but that cable is always going to be a limitation. If you’ve never used a proper wireless gaming mouse, you don’t realise how much the cable affects your aim until it’s gone.

Against other budget wireless mice (the PEEH wireless or generic Amazon brands), the G305 is in a different league. Most sub-£30 wireless mice use Bluetooth or cheap 2.4GHz dongles with 8-16ms latency. The G305’s 1ms LIGHTSPEED connection is genuinely competitive-level wireless.

That tells you everything about what Logitech got right here. They identified the core features that matter for gaming (sensor, wireless latency, battery life) and nailed those, then stripped away everything else to keep the price down.

Here’s the value proposition in simple terms: the G305 uses the same HERO sensor and LIGHTSPEED wireless as Logitech’s £150 G Pro X Superlight. You’re paying less than a third of the price. What you’re giving up is weight (99g vs 63g), materials (plastic vs premium coating), and rechargeable battery (AA vs lithium).

For most gamers, those trade-offs are absolutely worth it. The sensor performance is identical. The wireless latency is identical. The battery lasts longer because it’s a replaceable AA rather than a rechargeable lithium that degrades over time.

At the budget end of wireless gaming mice, you’ve got three options: cheap wireless mice with poor sensors and high latency (£15-25), decent wired mice like the G203 (£25), or the G305 (currently around £33). The G305 costs slightly more but delivers genuinely competitive wireless performance. That’s exceptional value.

The performance is what matters. The sensor is flawless. The wireless connection is genuinely 1ms with zero dropouts. The battery lasts months. Everything else – the basic plastic, the lack of RGB, the mushy side buttons – these are cosmetic compromises that don’t affect gaming performance.

So who should buy this? If you’re a competitive gamer on a budget who wants proper wireless performance, buy the G305. If you’re a laptop user who needs a portable wireless mouse that actually performs in games, buy the G305. If you want to try wireless gaming without spending £100+, buy the G305.

Skip it only if you need RGB lighting, want premium materials and build quality, or require an ultralight design under 70g. For those needs, you’re looking at the Razer Viper V2 Pro or Logitech G502 X, both of which cost significantly more.
