Womier SK75 TMR Keyboard Review – Hefty HE Heaven?

This hefty beast is the WomierSK75 TMR, an all ali mag-switch keyboard with a few interesting choices. This is also only the second ever TMR board I’ve had in, so let’s look at this chonker and see if it’s worth your surprisingly little hard-earned cash. Just to rattle off the KSPs, this obviously uses TMR switches, features an 8000Hz polling rate both wirelessly and wired, has an 8000mAh battery inside (that’s twice most keyboards) and offers tri-mode connectivity. Oh, and the TWO KILOS of aluminium. That too.

I’ll start with a tour. From the front this looks like a fairly typical 75 percent board. You’ve got the main keys, F keys, arrow keys, and a slim-line set of page up/down, end, home and delete. Optionally you get a nice red, yellow, green and blue set of caps for WASD, and Mac keys. Otherwise you have some double-shot caps with a black outer and blue inner. The caps aren’t shine-through, which for me is a pretty big shame. You do of course have an RGB backlight, although it’s weirdly dim, and without shining through the caps it feels a little pointless personally. Looking at the back of the board though, that is genuinely really pretty. They have this sort of purple and green plate on the bottom that looks amazing, plus the USB C port on top, and that’s it. No adjustable feet, the height they give you is the height you get. 

The shell itself is an absolute lump of aluminium. It’s thick, heavy, and gives a very deadening feel to the sound. It’s also infused with shiny specs, making this glitter in the light. It’s actually really pretty. While I personally don’t care so much about that – I tend to use my PC in darker environments so a dark shell like this would just blend into my desk, it is really nice to look at in the light. 

Now, you might be looking at this and thinking, well if the only hole in the shell is for the USB C port up top, how do you turn this thing on? Because I sure was! I don’t often have to look in the damn manual to find out how to do super basic stuff like turn it on, but here we are. You need to use the included keycap puller to remove the CAPS LOCK key, which will then reveal both the OUTEMU Team Mag switches, and the bloody power switch! WHY?!?! This is really annoying. This isn’t the first keyboard that put the power switch here, but I sure hope it’s the last because this is ridiculous. Once you do get it on though, you can either use it wired (by putting it in wired mode with FN + T) or wirelessly through the most generic cheap looking dongle possible (which you might need to enable with FN + R). If you’d rather use Bluetooth, that’s FN and Q, W or E for the three channels. FN and backspace shows you the battery level, FN and Win toggles Win lock, and FN and M swaps between Mac and Windows modes. Those are not customisable by the way, you’re stuck with those combos. The OS specific F keys row ones though, you can tweak those to your heart’s content. 

Speaking of customisation, Womier’s desktop software isn’t my favourite. It’s in Chinese by default, although the language settings are easy enough to find. It’d be nice if the software checked the system’s language settings and picked automatically, but it’s not a big deal. The software is a little clunky to use, offering 0.01mm increments in the actuation height, and taking a damn age to actually set that on the keyboard. You do have options for rapid trigger which resets the actuation height to a set distance below your current height, and of course all the hall effect style features like dynamic keystrokes and snap tap. Interestingly, I can’t find any option to control the polling rate. Now that’s not likely to be a real issue for a keyboard, but I’ve personally experienced older games (ie Killing Floor 2) stutter with a higher than 1KHz mouse. Anyway, the software does let you do just about everything you’d expect, so that’s fine enough.

Of course the software could do everything in the world, but if the typing experience sucks, you still wouldn’t buy it. Well luckily it doesn’t suck, it’s actually pretty nice. These OUTEMU Tea switches are a fair bit too light for my tastes – I think 40 grams of actuation force, and just 48 gram force max, so yeah these are super light, and for me that’s not something I enjoy. Still, the typing feel is still pretty nice thanks to that absolute chunk of ali the case is made from. Have a listen… To me this sounds pretty refined. Not as silent as I like it, but definitely nice. There’s a deadness to the sound that you really only get with this much mass, and I definitely like that.

When it comes to gaming, well first we need to talk latency. Luckily I built a tool to test just that, the open source latency testing tool (available at OSRTT.com by the way, link in the description!) and as always I’ve tested both wired and wireless, and at a few different actuation points, as generally the higher the actuation point, the faster the results. Just looking at this board itself, you can see just how much difference there is between the 1mm and 2mm actuation points. Three milliseconds versus 6! Mental! Also, the wireless only adds 0.7 milliseconds, so yeah in short both are great. Dropping the best results from wired and wireless into the field, you can see that this thing is actually the fastest keyboard I’ve tested. The 2mm result is pretty midfield, but at 1mm… it’s the fastest by over a millisecond. Mental. 

For actually gaming though, well obviously it’s rather good. It has all the features you’d expect, and that super light feel starts to make a little more sense. It feels more in its element when you’re using WASD to sprint around. To me this is a better gaming keyboard than it is for typing – not that it’s actually all that bad for typing, but still – and it’s really good for gaming. Hell, even that low latency means it gives you a fractional competitive advantage, and that’s pretty cool. I enjoyed gaming on this.

Now the difficult part, the price tag. Amazingly, at least at the time of filming in the UK, this thing is just £137. Now for a regular keyboard that would be into the premium bracket, but for TWO KILOS OF ALUMINIUM?? That’s insane. I’m really surprised – in a good way – at the price and quality this thing offers. Oh god I also forgot that should you prefer different switches, you absolutely can. The software supports a handful of magnetic switches, and the board itself actually has Cherry MX hotswap sockets for mechanical switches, should you be that way inclined. I don’t know why, considering TMR sensors are more accurate, sensitive, and efficient, but the option is there. All of that, for less than £150? Damn. This isn’t for me personally, at least with these switches, but I can wholeheartedly recommend it if you like the sound of lighter switches. Great job Womier!
