The membrane keyboard you’ve been using works, technically. But it feels mushy. The keys wobble. Your mates with mechanical boards won’t shut up about how much better theirs feel. You’re curious, but not £150 curious.

This is where the Corsair K55 RGB PRO sits. It’s not a mechanical keyboard. It uses rubber dome switches, the same technology as the basic keyboard that came with your first PC. But Corsair has dressed it up with RGB lighting, dedicated macro keys, media controls, and IP42 dust and spill resistance. At £59.99, it’s positioned as a budget gaming keyboard that gives you the aesthetic without the mechanical price tag.

I’ve spent a month with this keyboard, using it for everything from spreadsheet work to late-night gaming sessions. I’ve tested the macro keys, pushed the software to its limits, and yes, I’ve spilled tea on it (accidentally, but it counts as testing). Here’s what you actually need to know about whether a membrane keyboard can deliver a gaming experience worth paying for in 2026.

If the price and features align with what you need, you can CORSAIR K55 RGB PRO Membrane Wired Gaming Keyboard – IP42 Dust and Spill-Resistant – 6 Macro Keys with Elgato Integration – iCUE Compatible – QWERTY UK – PC, Mac, Xbox – Black to check current availability.

How It Types

Let’s address this immediately: the Corsair K55 RGB PRO uses membrane switches, not mechanical ones. If you’re coming from a mechanical keyboard expecting that crisp, defined actuation point, you’ll be disappointed. This is rubber dome technology, where pressing a key compresses a rubber dome until it makes contact with a circuit board beneath.

That said, membrane switches aren’t automatically rubbish.

The key feel here is soft and quiet. There’s no tactile bump, no audible click, just a smooth press down until you bottom out. The actuation force is light, requiring minimal pressure to register a keystroke. After a month of daily use, I found the typing experience perfectly acceptable for general work. I wrote several thousand words on this keyboard without developing any strain or fatigue.

Gaming performance is where membrane keyboards typically show their limitations, but the K55 RGB PRO handles it better than expected. Corsair claims full n-key rollover, meaning every keypress registers independently regardless of how many keys you’re holding simultaneously. I tested this with online rollover checkers and confirmed it works as advertised. In fast-paced games like Apex Legends and Counter-Strike 2, I never experienced missed inputs or ghosting.

The keycaps are ABS plastic with a slightly textured finish. They’re not the premium PBT you’d find on enthusiast boards, and they will develop shine over time. After a month, the WASD keys and spacebar were already showing early signs of wear. This is standard for ABS keycaps at this price point.

Here’s something that genuinely frustrated me: the lack of adjustable actuation. With mechanical switches, you can choose between different actuation points and forces. Some people prefer light linears for rapid-fire gaming. Others want heavy tactiles for deliberate typing. The K55 RGB PRO gives you one option, and you either adapt to it or you don’t. For me, the light actuation occasionally resulted in accidental keypresses when resting my fingers on the home row. It’s not a deal-breaker, but it’s worth noting if you’re a heavy-handed typist.

The six dedicated macro keys on the left side are brilliant for productivity and gaming. I programmed them through Corsair’s iCUE software with shortcuts for Adobe Premiere, Discord mute toggles, and frequently used text snippets. They’re positioned far enough left that I never accidentally hit them during gaming, but close enough to reach without stretching. This is proper functionality that you won’t find on most keyboards under £100, mechanical or otherwise.

The dedicated media controls at the top right – volume wheel and playback buttons – are equally useful. I use them constantly. No more fumbling with Fn key combinations to pause music or adjust volume mid-game. The volume wheel has a satisfying, notched rotation that gives tactile feedback.

Build Quality

The K55 RGB PRO feels substantially better built than its price suggests. The chassis is primarily plastic, but it’s thick plastic with minimal flex. I tried the keyboard twist test, gripping opposite corners and torquing. There’s some give, but nothing concerning. For comparison, I’ve tested mechanical keyboards at twice this price with worse chassis rigidity.

The stabilisers on the larger keys – spacebar, both shifts, enter, and backspace – are where most budget keyboards fall apart. Stabiliser rattle is that horrible rattling sound when you press a long key off-centre. It’s the audio equivalent of nails on a chalkboard for anyone who’s spent time with quality keyboards.

The K55 RGB PRO’s stabilisers are… acceptable. The spacebar has a slight rattle when struck hard on the far left or right edges, but it’s minimal. During normal typing and gaming, I rarely noticed it. The shift keys and enter are better, with virtually no rattle. This is genuinely impressive for a membrane board at this price. Corsair clearly spent time on stabiliser tuning, and it shows.

The included palm rest attaches magnetically to the bottom edge of the keyboard. It’s made of soft rubber with a textured surface that prevents your wrists from sliding. I found it comfortable during extended sessions. The magnetic attachment is strong enough that the palm rest doesn’t shift during use, but easy enough to remove when you want a more compact setup.

One design choice I reckon is dodgy: the permanently attached USB cable. It’s not detachable. If the cable gets damaged, you’re either attempting a repair or buying a new keyboard. Detachable USB-C cables are standard even on budget mechanical boards now. This feels like an unnecessary cost-cutting measure.

The IP42 rating means the keyboard is protected against objects larger than 1mm (like dust) and water spray at an angle up to 15 degrees from vertical. In practical terms, it’ll survive a spilled drink if you act quickly. I tested this by deliberately knocking over a mug of tea onto the right side of the keyboard. I immediately unplugged it, turned it upside down to drain, and left it to dry for 24 hours. After drying, it worked perfectly with no sticky keys or dead LEDs. Your mileage may vary depending on what you spill and how quickly you react, but the IP42 rating isn’t just marketing.

Software Experience

The K55 RGB PRO uses Corsair’s iCUE software for customisation. If you own other Corsair peripherals – mice, headsets, RGB fans – iCUE can synchronise lighting across all of them. If you don’t, iCUE is a 500MB download that wants to run constantly in the background.

Here’s my honest take: iCUE is bloated software that does too much. It’s trying to be a universal control centre for every Corsair product you might own, which means it’s packed with features you’ll never use. The interface is visually busy, with multiple tabs and sub-menus for different device categories. Finding the specific setting you want requires clicking through several screens.

That said, once you get past the learning curve, iCUE is functional. Setting up macros is straightforward – you click the macro button, record your keystrokes or shortcuts, and assign it to one of the six macro keys. You can add delays between keypresses, which is useful for complex game macros or automation sequences.

The RGB customisation offers six onboard lighting effects without software, controlled by keyboard shortcuts. These include static colour, rainbow wave, colour shift, and a few others. They’re fine if you want simple RGB without installing software. If you want more control – setting specific colours for individual keys, creating custom lighting effects, or syncing with other devices – you’ll need iCUE.

I created a custom lighting profile where the WASD keys, spacebar, and shift were bright red, while the rest of the keyboard was a dim blue. This made it easier to find gaming keys in a dark room. The per-key RGB works well, with even lighting across each keycap. There’s no significant light bleed around the keys.

One genuinely useful iCUE feature: integration with Elgato Stream Deck software. If you’re a content creator using Stream Deck for stream control, you can program the K55’s macro keys through Stream Deck software instead of iCUE. This creates a unified workflow where your keyboard macros and Stream Deck buttons are managed in one place. It’s a niche use case, but if you’re in that niche, it’s cracking functionality.

The keyboard stores one lighting profile and one set of macro assignments in onboard memory. This means you can set up your preferred configuration, save it to the keyboard, and it’ll work on any PC without installing iCUE. This is proper design – you shouldn’t need software running 24/7 just to maintain your settings.

Comparison: How Does It Stack Up?

The comparison reveals the K55’s positioning clearly. It’s more expensive than basic membrane boards but offers features they don’t have. It’s cheaper than mechanical keyboards but sacrifices the switch feel. The question is whether the feature set justifies the price premium over a £20 basic keyboard.

For me, the macro keys alone justify the difference. If you use productivity shortcuts, stream, or play MMOs with complex rotations, six programmable keys are genuinely useful. The Logitech G213 is the closest competitor, offering similar membrane switches and RGB at a comparable price, but it lacks dedicated macro keys. The Redragon K552 gives you actual mechanical switches for less money, but it’s a compact 87-key layout with no numpad, no macro keys, and clicky switches that will annoy everyone within earshot.

Is the K55 worth £25 more than a basic keyboard? If you want RGB, macros, and media controls, yes. Is it worth £100 less than a budget mechanical? That depends entirely on whether you care about mechanical switches. If you’ve never used a mechanical keyboard and don’t know what you’re missing, the K55 will serve you perfectly well.

Acoustics

One of the few genuine advantages of membrane switches: they’re quiet. The K55 RGB PRO produces a soft, muted sound when typing. There’s no sharp click, no resonant thock, just a gentle tap as the keys bottom out against the plate. If you work in a shared space or game late at night with family sleeping nearby, this is a significant benefit.

I recorded typing sessions and measured the sound at approximately 45-50 decibels from a normal typing position. For context, that’s quieter than normal conversation (60dB) and significantly quieter than mechanical keyboards with clicky switches (65-70dB). Even mechanical keyboards with silent switches typically measure 50-55dB.

The spacebar is the loudest key, producing a slightly hollow thunk when struck firmly in the centre. It’s not annoying, but it’s noticeably louder than the alphanumeric keys. The stabilised keys (shifts, enter, backspace) are similarly quiet to the main keys.

There’s a tangent worth mentioning here. I once worked in an office where a colleague insisted on using a keyboard with Cherry MX Blue switches – the loudest, clickiest mechanical switch available. Every keystroke was a sharp CLICK that echoed across the room. After two weeks of this auditory assault, the team collectively bought him a membrane keyboard and presented it as a “gift.” He got the message. If you’re that colleague, the K55 RGB PRO is your redemption.

The quiet operation doesn’t mean the keyboard feels cheap or mushy. The key travel is approximately 3.2mm, which is standard for membrane boards. There’s enough travel that you get tactile feedback from bottoming out, but not so much that it feels sluggish. The return spring is responsive, snapping keys back to the top position quickly.

What Other Buyers Think

With 4,293 reviews averaging 4.5 stars, the K55 RGB PRO has substantial real-world feedback. I spent time reading through verified purchase reviews to identify common themes beyond my personal experience.

The most common praise focuses on value for money. Buyers consistently mention getting “premium features at a budget price,” specifically calling out the macro keys, RGB customisation, and build quality. Many reviews come from people upgrading from basic keyboards who are impressed by the feature set.

The quiet operation receives frequent positive mentions, particularly from buyers who game late at night or work in shared spaces. Several reviews specifically mention buying the K55 to replace loud mechanical keyboards that were disturbing family members.

The IP42 spill resistance has real-world validation. Multiple reviews describe spilling drinks on the keyboard and having it survive after drying. One reviewer spilled an entire pint of beer on it, cleaned it immediately, and reported it still worked perfectly months later. Obviously, spill resistance isn’t an invitation to be careless, but it’s reassuring to know the protection is genuine.

The most common criticism is predictable: people who expected or wanted mechanical switches are disappointed. Several reviews mention buying the K55 thinking it was mechanical based on the “gaming keyboard” marketing, then feeling let down by the membrane switches. This is user error – Corsair doesn’t claim the K55 is mechanical – but it’s worth noting if you’re considering this keyboard specifically for mechanical switches.

Some buyers report the RGB lighting failing after 6-12 months, with individual keys or entire zones going dark. This isn’t widespread – it appears in maybe 5% of reviews – but it’s worth considering. Corsair’s warranty should cover LED failures, but it’s an inconvenience regardless.

A handful of reviews mention the permanently attached cable as a negative, echoing my own criticism. In 2026, detachable cables should be standard even on budget keyboards.

Interestingly, several reviews come from people building budget gaming PCs who want the RGB aesthetic without spending mechanical keyboard money. For this use case – where appearance matters as much as functionality – the K55 delivers exactly what buyers want.

Is This Right For You?

The Corsair K55 RGB PRO makes sense for specific buyer profiles. If you’re any of these people, it’s worth considering:

Budget-conscious gamers who want RGB aesthetics and gaming features without spending £100+ on a mechanical keyboard. You’ll get macro keys, customisable lighting, and responsive performance for less than half the price of entry-level mechanical boards.

Office workers or students who need a quiet keyboard for shared spaces. The membrane switches are quiet enough for open offices or dorm rooms where loud mechanical keyboards would be inappropriate.

Content creators and streamers who need programmable macro keys for shortcuts and stream control. The Elgato Stream Deck integration is particularly useful for this group.

Parents gaming after kids’ bedtime who need a quiet keyboard that won’t wake sleeping children. The 45-50dB typing sound is significantly quieter than mechanical alternatives.

The K55 RGB PRO doesn’t make sense if you’re:

A mechanical keyboard enthusiast who values switch feel and customisation. The membrane switches simply can’t replicate the tactile experience of mechanical switches. You’ll be disappointed.

Someone wanting a premium, long-lasting keyboard to use for 5-10 years. The ABS keycaps will wear, and membrane switches have shorter lifespans than mechanical switches. This is a 2-3 year keyboard, not a decade investment.

A competitive esports player who needs every possible advantage. While the K55 performs adequately, mechanical keyboards with faster actuation and lighter switches provide marginal performance benefits that matter at the highest skill levels.

Final Thoughts

After a month of daily use, I’m genuinely impressed by what Corsair has delivered at this price point. The K55 RGB PRO doesn’t try to fake being a mechanical keyboard. It’s honest about what it is: a well-executed membrane board with useful features and solid build quality.

The six macro keys are the standout feature. I use them constantly for productivity shortcuts and gaming macros. Combined with the dedicated media controls, they provide functionality that improves the daily computing experience in tangible ways. The IP42 spill resistance adds peace of mind, and my tea-spilling test confirms it’s not just marketing.

The membrane switches are the limiting factor. They’re quiet, responsive, and perfectly adequate for gaming and typing. But they’re not mechanical switches. If you’ve experienced quality mechanical keyboards, you’ll notice the difference immediately. The lack of tactile feedback and defined actuation point makes the typing experience less engaging.

At £59.99, the K55 RGB PRO occupies an interesting market position. It’s expensive for a membrane keyboard but cheap for a gaming keyboard with this feature set. The value proposition depends entirely on whether the macro keys, RGB lighting, and media controls matter to you. If they do, this is a solid choice. If you only care about key feel, save your money for a mechanical board.

Would I recommend this keyboard? Yes, with clear caveats. If you’re on a budget, need macro keys, want RGB aesthetics, and don’t mind membrane switches, buy it. If you’re saving for a mechanical keyboard or already own one, skip it. The K55 RGB PRO is a good membrane keyboard, but it’s still a membrane keyboard.
