Logitech G915 X LIGHTSPEED TKL: Specs, Features, Pros & Cons
Low profile is the whole decision here; everything else follows from it. The keys travel roughly half the distance of a normal mechanical switch, which makes typing quieter and the board remarkably thin.
Whether you like it is preference rather than quality — people coming from a laptop keyboard usually take to it immediately, and people coming from a full-travel mechanical often do not. Beyond that it is a well-equipped wireless tenkeyless with a rotary knob, three connection modes and onboard profiles.

Editor’s note
The G915 X is the low-profile option here, and low profile is the whole decision — everything else follows from it.
The keys travel roughly half the distance of a normal mechanical switch, which makes typing faster and quieter and the board itself remarkably thin. Whether you like it is a matter of preference rather than quality; people coming from a laptop keyboard usually take to it immediately, people coming from a full-travel mechanical often do not.
The standout number is battery: a quoted 1,000 hours, several times anything else here, across tri-mode wired, 2.4 GHz and Bluetooth connection. In practice that means charging it a handful of times a year.
The trade is flexibility. The switches are not hot-swappable, so the feel you buy is permanent, and there is no Hall-effect sensing — no adjustable actuation, no rapid trigger, no analog input. Polling is 1,000 Hz. This is a well-made conventional keyboard, not a competitive-gaming instrument.
The build is otherwise good: a brushed aluminium-alloy top plate, PBT keycaps, per-key RGB, a rotary knob, media controls and onboard profiles, in an 87-key TKL layout at 860 g.
Buy it if you want a thin, quiet, extremely long-lasting wireless keyboard and low-profile keys appeal. Buy a full-travel board if you are unsure about the switch height, and a magnetic one if rapid trigger is what you are shopping for.

The bottom line
The Logitech G915 X LIGHTSPEED TKL earns a VS Score of 35, trailing most of the 101 keyboards we compare here, at least on the spec sheet. It stands out for more connection options, rotary knob and onboard profiles. Just be aware of a much lower polling rate and the missing hot-swappable switches before you buy. Weigh those trade-offs against what matters most to you.
The VS Score is calculated from the weighted specifications above, compared with every other keyboard we track — a shortlisting guide, not a substitute for your own priorities. See how we score.
