Logitech G915 X LIGHTSPEED TKL Review: Slim and Solid

The Logitech G915 X LIGHTSPEED TKL is a slim, wireless, tenkeyless mechanical keyboard aimed at gamers and desk users who want low-profile switches without being tied to a cable. This review is based on the manufacturer's specifications and on what independent expert reviewers report, not on hands-on testing. It is positioned in the mid-range price tier, though reviewers call the price high for what it offers.

Logitech G915 X LIGHTSPEED TKL review: what it is and who it's for

The G915 X is a tenkeyless board, meaning it drops the number pad to leave more room for your mouse. It pairs that compact layout with low-profile GL mechanical switches. The keyboard combines a premium build, three connection modes and long battery life.

In short, it suits wireless low-profile fans who want a premium build and flexible connectivity. If you want the quietest possible typing, switches you can swap yourself or the lowest price, you may want to keep looking. We'll cover why below.

Design and build quality

The G915 X pairs a brushed aluminum top plate with double-shot PBT keycaps. Reviewers consistently praise the premium, sturdy feel that results. The keycap material matters day to day: double-shot construction means the legends are moulded into the cap rather than printed on the surface, and PBT is a plastic commonly chosen for keycaps that need to hold up to heavy use.

The board is about 23 mm high, which is the defining trait of the low-profile approach. Your hands sit closer to the desk, and the keyboard takes up little vertical space. With its tenkeyless layout, it has a compact footprint on the desk. At 860g it has some heft, which fits the metal-topped construction; it isn't a featherweight you'll be tossing around, though it is built to be wireless.

A nice touch for everyday use is the set of soft-touch media keys and the metal volume roller. Reviewers single these out, calling the roller smooth. If you adjust volume often while gaming, working or listening to music, a dedicated roller is quicker than a function-key combination.

Switches and typing feel

The keyboard uses GL low-profile mechanical switches, available in Linear, Tactile or Clicky versions. That choice is useful because it lets you pick a feel that suits your habits:

• Linear switches press smoothly with no bump, a common preference for gaming.
• Tactile switches have a bump at the actuation point that you can feel without much noise.
• Clicky switches add an audible click on top of the tactile bump.

Actuation happens at 1.3 mm, with a total travel of 3.2±0.25mm. That shallow actuation point is what gives low-profile boards their quick, responsive character, and reviewers describe the G915 X's switches as quick and responsive. The report rate is a maximum of 1ms.

There is a catch that comes up repeatedly in expert feedback. A common criticism is that typing sound can be rattly and slightly metallic. If you share a room or work in a quiet office, that's worth weighing up. The switches are also not hot-swappable, so you can't swap in different switches later. The switch type you choose when you buy is the one you'll live with.

Connectivity and wireless performance

The headline feature is tri-mode connectivity: a 2.4 GHz LIGHTSPEED dongle, Bluetooth 5.0 and a wired USB connection. In practice that means:

• LIGHTSPEED 2.4 GHz is the dongle-based wireless mode, suited to gaming at your main desk.
• Bluetooth is handy for pairing with a laptop, tablet or other device when you don't want to use the dongle.
• Wired USB works with the 1.8m USB A to C cable listed in the specs and lets you connect by cable.

Reviewers praise this flexibility. One limit to note: only one Bluetooth device can be paired at a time. If you hoped to switch between several Bluetooth devices at the press of a key, this isn't built for that. You can, however, move between the dongle, a Bluetooth pairing and the cable.

Battery life

Battery life is rated at up to 42 hours with RGB at full brightness, which reviewers count among the keyboard's strengths. Turn the lighting off and the rating rises to up to 1000 hours. Those are manufacturer figures, so real-world results will depend on your lighting settings and usage, but the numbers show that you don't need to charge often unless you run the lighting hard.

The battery is rechargeable and not user replaceable. The keyboard also supports a wired USB-C connection.

Features and software

Lighting is per-key LIGHTSYNC RGB with about 16.8 million colors, managed in Logitech's G HUB software. You can customise effects and colours key by key, and KEYCONTROL lets you assign up to 15 functions per key. That's a flexible system if you like building macros or layered shortcuts for games, editing or other work.

The G915 X is covered by a 2 Year Limited Hardware Warranty.

What experts like and what they criticise

Among the two expert scores we found, TechRadar rates the keyboard 3.5 out of 5 and CGMagazine gives it 9/10, which averages out at 8/10 across 2 expert reviews. That's a respectable result with a visible gap between the two verdicts, which tells you something: the keyboard has real strengths, but whether it satisfies you depends on how much its weaknesses matter to you.

What reviewers praise:

• The tri-mode connectivity
• The premium, sturdy build with its aluminum top plate
• The long battery life, with RGB at full brightness
• The quick, responsive low-profile switches in linear, tactile or clicky
• The smooth volume roller and dedicated media keys

What reviewers criticise:

• A common criticism is that the price is high for what it offers
• The typing sound can be rattly and slightly metallic
• The switches are not hot-swappable
• Only one Bluetooth device can be paired at a time

The price criticism is the one most likely to affect your decision. The keyboard is in the mid-range price tier, but reviewers call the price high for what it offers.

Who should buy it, and who should skip it

Buy it if:

• You want a wireless low-profile keyboard with a premium, metal-topped build.
• You like the idea of a 2.4 GHz dongle for gaming, Bluetooth for other devices and a cable as a fallback.
• You want long battery life and don't want to think about charging often.
• You want to pick between linear, tactile and clicky switches.
• A tenkeyless layout suits your desk and mouse space.

Skip it if:

• You want quieter typing, as a common criticism is a rattly, slightly metallic sound.
• You want hot-swappable switches so you can change the feel later.
• You need to switch between several Bluetooth devices.
• You want the lowest possible price, since reviewers see the price as high for what it offers.

How it fits in its category

The G915 X is a low-profile wireless keyboard that pairs a slim shape and a 1.3 mm actuation point with an aluminum top plate, tri-mode connectivity and per-key lighting. If you prefer a taller board with swappable switches, or you prioritise price above everything else, a different style of keyboard may fit better. If low-profile feel and wireless flexibility are what you're after, this is the kind of keyboard the format is built for.

Verdict

The Logitech G915 X LIGHTSPEED TKL is a well-built, flexible wireless low-profile keyboard whose main strengths are its sturdy construction, tri-mode connectivity, long battery life and responsive switches. Its weaknesses are just as clear: reviewers find the price high, the sound can be rattly and slightly metallic, the switches can't be swapped and Bluetooth is limited to one paired device. With an 8/10 average across 2 expert reviews, it's a solid choice for buyers who value its particular strengths and can live with those compromises.
