Logitech G915 X LIGHTSPEED Review

When I first unboxed the Logitech G915 X LIGHTSPEED, I knew right away this wasn’t going to be an ordinary keyboard experience. For one, the sheer thinness of the chassis is almost disorienting. It’s incredibly sleek, so much so that I caught myself just admiring it before I even plugged it in. But this isn’t a keyboard that’s just about looks. Logitech has been refining its LIGHTSPEED line over the years, and the G915 X feels like a matured and highly refined culmination of their work.

Over the past two months, I’ve used it as my daily driver for both gaming and work, and I’ve come to the conclusion that this keyboard is as close as it gets to being perfect for a hybrid lifestyle. It handles high stakes competitive gaming and extended writing sessions equally well, though it's not without a few quirks that are worth calling out, most notably, the key placement takes some getting used to, and even after many hours of use, I still occasionally hit the wrong key. In particular the G5 key instead of the CTRL key, as it occupies the left most key on the keyboard, one traditionally kept for CTRL.

The G915 X LIGHTSPEED is thin. Like, absurdly thin. It’s a full-size keyboard (there’s also a TKL version), yet it somehow feels smaller due to the low profile. It’s made from aircraft-grade aluminium on the top and a steel-reinforced plastic on the bottom, which together make it feel incredibly premium but also rigid enough that you can type with force without flexing the deck. It doesn’t creak, bend, or rattle, everything about the construction oozes quality.

This is easily one of the best built keyboards I’ve ever laid hands on, and the matte finish helps it resist fingerprints surprisingly well. The brushed aluminium gives it a futuristic look without being garish, and the low-profile floating keycaps add to the overall aesthetic. There’s no included wrist rest, which some people might miss, but honestly, the low profile makes it comfortable enough that I didn’t feel I needed one, and I say this as someone who types for hours daily.

Typing on this keyboard is a very different experience if you’re used to traditional Cherry MX or equivalent. The short travel makes it feel incredibly responsive, meaning you barely have to press, and the key actuates. This is fantastic for gaming, you can react quickly and with minimal effort, but it does mean you need to be more deliberate when typing. It’s very easy to accidentally press the wrong key, especially early on, something I did A LOT in the first few weeks.

As I’ve already mentioned, I found myself hitting “G5” instead of CTRL on more than one occasion, or “Caps Lock” instead of “A”. It’s hard to explain exactly why, the keys are full-sized, after all, but it seems to come down to the spacing and the shallow press depth. You’ll adapt over time, but even after several weeks, I still find myself occasionally misfiring a key, particularly during fast paced typing. Still, once you get the hang of it, the typing experience is exceptional. It’s light, fluid, and precise. The keycaps feel sturdy and high quality under the fingers, and there’s minimal wobble or looseness..

Make no mistake, this keyboard is primarily made for gaming. Logitech’s LIGHTSPEED wireless connection is, as always, impressive. With no noticeable lag, dropouts, or hiccups. In fast-paced games like COD Zombies and Fortnite, the responsiveness felt identical to a wired connection.

The switches are ideal for games where precision and quick reflexes matter. The shorter actuation distance means you can move, shoot, reload, and dodge a fraction faster than you could on something standard. Over long gaming sessions, the lightweight feel of the keys also helps prevent fatigue, I didn’t feel like I was hammering my fingers against plastic for hours.

The RGB lighting is another win for the gaming side of things. It’s per-key, fully customisable, and supports LIGHTSYNC integration, meaning the possibilities are endless through dynamic effects. I didn’t personally use many dynamic effects, but I did set different profiles for certain games. For example, FPS controls lit in Teal, abilities in red, function keys in white), and the visual indication helped reduce in game errors.

There are also a multitude of programmable G-keys on the full-size version, which are great for MMOs or productivity macros. I bound a few simple macros (quick reload , melee, grenade, and a screenshot/record clip combo) and they worked flawlessly.

The Logitech G915X is just as good at handling serious work as it is at gaming. I write a lot of, emails, articles, and reviews, and the G915 X LIGHTSPEED has been excellent for productivity. The typing experience is quiet enough that I can use it during Zoom meetings or late at night without waking anyone up. It’s not silent, but it’s very well dampened.

The layout is standard enough that you don’t need to relearn anything if you’re coming from a typical full-size keyboard. The media keys are a godsend, I use the volume roller constantly, and the dedicated play/pause/skip buttons are so much better than function-layer shortcuts. The brightness and game mode keys also let you quickly toggle lighting or disable specific keys during gaming (goodbye, accidental Windows key presses).

Switching between devices is another highlight. The G915 X supports three modes: LIGHTSPEED (via USB dongle), Bluetooth, and wired USB-C. I often switch between my gaming desktop, work laptop, and tablet, and having those connections mapped to specific keys means I can toggle between them in seconds. It’s seamless and something that more keyboards need to offer.

Battery life is solid. With RGB at 100%, you’ll get around 40 hours of use, depending on usage. Turn the brightness down or turn the lighting off entirely and you’ll go over 100 hours easily. I plug it in once every few days, usually overnight, and haven’t had any power anxiety.

Logitech G HUB isn’t perfect, but it’s improved significantly. Once you get used to the interface, it’s powerful. You can reprogram every key, set up lighting profiles, assign macros, and manage multiple device profiles. It also lets you sync effects across Logitech gear, like matching the G915’s RGB with a G502 X Plus mouse or G522 headset for the ultimate aesthetic.

No product is perfect, and while the G915 X gets a lot right, there are a few downsides worth mentioning.

The most obvious one is the key placement issue I mentioned earlier. Despite being a standard layout, the key spacing and low travel make it easier than expected to hit the wrong key. It's not an issue unique to this keyboard, but I've noticed it a lot with this one, possibly because the keys are so shallow. It feels like you're pressing keys faster than your brain can keep up with at times.

Also, while the keyboard is ultra-thin and minimalist, some users may miss having a wrist rest included. Given the price point, of around $300 AUD (at the time of writing this review), a wrist rest would have been a nice addition.

And speaking of price: this is a premium keyboard. There’s no way around that. It’s not cheap, and while I personally think it justifies its cost with performance, build quality, and features, not everyone will feel the same.

The Logitech G915 X LIGHTSPEED is the rare kind of keyboard that actually lives up to its hype. It’s thin, beautiful, and performs at an elite level in both gaming and productivity scenarios. The LIGHTSPEED wireless connection is as good as any wired option I’ve used, and the battery life, RGB customisation, and multi-device support round out an incredibly well thought out package.

It’s not perfect. The key spacing takes time to adjust to, and the price is steep. But if you’re looking for a truly wireless mechanical keyboard that doesn’t compromise on speed, style, or functionality, one that you can comfortably use for both work and play, this might be one of the best on the market right now.

It’s nearly perfect. A few small quirks hold it back from being flawless, but as an all rounder, the G915 X LIGHTSPEED is exceptional, and one of the few keyboards I’ve genuinely fallen in love with.
