Build and Design

The Womier SK75 TMR is a 75% keyboard: function row, arrow keys, and a short column of navigation keys on the right, with no numpad, knob, or screen. The case is aluminum with a top-mounted, non-flex-cut FR4 plate, and Womier lists it at 321 x 140 x 38 (47) mm and about 2,000 g, which puts it in the Keychron Q1 HE’s weight class rather than the K2 HE’s. Keycaps are Cherry-profile double-shot PBT, and it comes in black or white.

The switches are Womier’s own Void magnetic linears with a full POM stem and housing, rated at 40 g actuation and 3.5 mm total travel. Instead of Hall effect sensors, the PCB uses TMR (tunneling magnetoresistance) sensors. Both read a magnet in the stem to track key position; TMR sensors are marketed as lower power and more temperature-stable. Independent testing is limited, so treat those as manufacturer claims.

The most unusual design decision is the hybrid hot-swappable PCB, which Womier lists as cross-compatible with magnetic and standard mechanical switches. Most magnetic boards cannot take conventional switches at all. Here you can mix them: magnetic on movement keys, tactile mechanical on the alphas. Mechanical keys lose rapid trigger and adjustable actuation but gain a tactile bump no magnetic switch offers.

Performance and Daily Use

Every magnetic-keyboard feature that matters is present. Rapid trigger resets a key the moment you begin lifting it, with zero deadzone. Adjustable actuation runs from 0.1 to 3.5 mm per key in 0.01 mm steps, finer than the 0.1 mm steps on most rivals. DKS lets one key fire different actions at different depths, and SOCD and Snap Tap are included. Turn those off before competitive play; Valve blocks the behavior on official CS2 servers and Riot prohibits it in Valorant.

Connectivity is tri-mode: USB-C, 2.4GHz receiver, and Bluetooth. Womier lists 8,000Hz polling over both cable and 2.4GHz with a 0.125 ms wired latency claim, which would make it one of very few wireless magnetic boards to exceed 1,000Hz wirelessly. Independent measurements are scarce. Bluetooth polling is not specified. The 8,000 mAh battery is large for a 75% board, but Womier does not publish runtime hours; expect RGB and 8,000Hz wireless polling to shorten it substantially.

Configuration runs through the downloadable SK75 TMR Driver V3.1.0 for Windows and macOS. It covers the essentials but lacks the refinement of the browser-based Wootility or Keychron Launcher. This is the board’s clearest weakness.

Who Should Buy It

Buy the SK75 TMR if you want an aluminum wireless 75% magnetic keyboard for gaming and typing without paying $200 or more. At $159 list, and regularly $128 on sale at Womier, it undercuts the Keychron Q1 HE by a wide margin and, on sale, the K2 HE as well, while listing faster polling, a heavier case, and the hybrid switch option. It is also the board to buy if you want tactile switches on your typing keys and magnetic switches on WASD in one keyboard.

Who Should Skip It

Skip it if software polish and long-term firmware support are priorities; Wooting and Keychron have the track record. Skip it if you are on a Mac and want Mac keycaps and a hardware OS toggle in the box, where the Keychron K2 HE is the easier choice. Skip it if you prefer the soft feel of a gasket mount, since this is a firmer top-mount board. And skip it if you compete at events that restrict hardware, since a lesser-known brand can complicate equipment checks.
