Womier SK75 TMR Gaming Keyboard Review

I hadn’t heard of Womier before testing its new SK75 TMR gaming keyboard. I went in with an open mind and I was treated to a very impressive bit of kit. It’s a 75% board that aims to deliver enthusiast-grade build quality while leaning hard into modern magnetic-switch performance. It’s a rapid trigger-focused keyboard built for reactive inputs, but it also puts effort into acoustics and feel in a way many gaming-first boards don’t. Here is my review.

The TMR advantage

As you might guess from the name, the SK75 TMR uses TMR (Tunneling Magnetoresistance) sensing technology rather than traditional Hall Effect. This should make for more stable long-term accuracy and reduced drift. It supports actuation from 0.1mm and has a claimed 0.125 ms reaction time. Additionally, it supports 8,000 Hz polling across both wired and wireless connection, which is a significant achievement in this space.

Another huge win for the SK75 TMR is its Mag-Mech hybrid hot-swap PCB. This lets you install magnetic switches and standard mechanical switches on the same board, opening the door for a practical “best of both worlds” build. You can keep magnetic switches on movement and ability keys for gaming responsiveness, while using mechanical switches elsewhere for a more traditional typing feel.

Connectivity is tri-mode, with USB-C, Bluetooth 5.0, and 2.4 GHz wireless, backed by a large 8000mAh battery. Though I often just keep my keyboard plugged in at my desk, as it’s one less thing to worry about recharging, I do appreciate a big battery for those occasions where I want to take my keyboard with me.

The most powerful app

It’s in the software where the SK75 TMR can really be made to shine. Functions such as Rapid Trigger, Snap Key, and Multi-Trigger can be used alongside classic full remapping and macro support. Take the time to customize during that first setup and you’ll have a keyboard that punches well above what its price tag might suggest. 

Performance is where the SK75 TMR really earns its name. Rapid Trigger feels crisp and predictable, and the board stays consistently responsive whether it’s plugged in or running over the 2.4GHz dongle. That wireless 8000Hz experience is a big deal if you want a clean setup but don’t want the usual drop-off in speed. 

Feels like quality

The aluminum case gives the SK75 TMR a dense, stable footprint that doesn’t shift once it’s on the desk. The internal dampening and top-mount structure do a strong job shaping acoustics too, keeping the sound deep and controlled rather than hollow or metallic.

The hybrid hot-swap support is more than a gimmick. It’s genuinely useful for people who love magnetic performance for certain keys but don’t want their entire typing experience to feel like a pure gaming tool. This flexibility is still extremely rare, so it really helps the SK75 TMR stand out from the crowd. 

The one issue

When it comes to downsides, I really only have the one. While the software can be powerful, it can be difficult to parse. Compared to more mainstream competitors, the app is cluttered and could use some refinement.
