Incredible Value and Performance

SpencerDecember 23, 2025

Pleasantly surprised by the quality, feel, and function of this keyboard. I’m selling my mechanical Logitech and Corsair now that I have this. It actually feels better and is 1/3 the price. Sounds nice and thocky as well. I may add another keyboard from this brand to my collection in the near future. Read more

Great keyboard!

kbible0518@gmailJune 8, 2025

The media could not be loaded. Bought this for my 10yr old gamer son. This is his review. He loves the RGB, beautiful colors that can be changed. He loves the sound of the keys. The sound of the keys are amazing and soothing. I enjoy the sound too. He also loves the fact that it is wireless. Great quality, highly recommend. He has a corsair and a razer. This is his favorite and good deal for what you get. Read more

USB Dongle stopped working 5 months later, also now stuck in FN mode

RichardSeptember 17, 2025

Keyboard is still working fine, months after buying it. Only issue is that the 2.4ghz dongle that came with the keyboard, no longer works. And the keyboard wont connect to my pc via bluetooth, which means I have to use it wired. A little disapointed, its a good looking keyboard, great for gaming, sucks at typing with, but now I cant use it wirelessly, which is the main reason I got it. Update: The Keyboard appears to be stuck in FN mode. No amount of redownloading the software, or reseting the keyboard, or waiting for it to die has worked. ALT + F4, CTRL + ALT + DELETE, and the windows key all do not work, even though say they are not disabled in the software menu. Product support and return window has ended for me, so im kinda screwed. Its been 5 months ajnnd 7 days of owning this keyboard and now its faulty. I'd look for a different keyboard from a different seller. Not being able to use the windows key is very annoying, same with alt f4 and ctrl alt delete, I use all three of these shortcuts often. Plus with no product support, and no way to get them to work, this keyboard has lost a lot of use from me. Read more

Great mechanical KB

Jared PowersMay 18, 2025

I was looking for a smaller wireless KB to replace my Alienware 510K KB and came across this brand. Honestly never heard of them until I started reading they were a spin off of Womier. I knew Womier made great KB so I figured I would take a chance and I'm glad I did. The keys feel great and the sound they make is very soothing! I love only had this KB for 2 days but its already my favorite (ordered last week around the 12/13th of May and it was suppose to be here the 15th but something happened to cause my package to be late not sure whose end it was on doesn't matter bc I have it now.) This KB has a strudy build and looks great. I purchased it for 52 dollars and honestly the value was great ive seen KB not as good as this one cost double or even triple just bc of the name on the box. Don't be a Melvin and overspend due to a company over compensating with their bank account to produce a commercial or advertisement with flashy lights and buzzwords. Just go with Womier and you'll be happy with your purchase and have money left over. Read more

Great but loud ASMR keys

kirstenOctober 31, 2025

Works great. I love the size, color and feel of the keyboard and keys. The keys do make louder than normal sounds when pressed. It is very much an ASMR thing. I, myself cannot stand ASMR and would prefer a quieter keyboard. Its also annoying when playing games with it. I dont hear it as much with my headphones on but my family hates how loud it is.
