Incredible performance!!
My brother loved this. He's an OSU and Geometry Dash player and the responsiveness, quality and performance fits just what he wanted. It sounds great, it's easy to use and setup. Definitely worth the price!!

Setup issues
The BTXETUEL SayoDevice OSU O3C is an excellent tool for improving gaming performance, but it’s extremely difficult to connect it to a computer—especially to a MacBook, in my case. Once the setup page opens in the browser, all the instructions are in Chinese, and clicking around randomly doesn’t seem to help at all. I eventually managed to get my computer to connect to the device, but I honestly have no idea what I did to make it work. The developers really need to put more effort into this aspect, otherwise it’s almost discouraging to invest in a gadget that appears not to function properly. However, once this nightmare is over, the device is very enjoyable and effective to use.

Good choice if you can’t get a wooting
Good quality build. Not the best, bad for how much it costs it’s a bit pricey, for 3 keys. the switches that come with are super annoying, but buying replacements is so easy that it’s not an issue. Very quick and responsive, not too wooting speed but probably second best. really portable and can move it out of the way at any moment. software is fine too.

Super bra produkt
Min son är ”over the moon” på detta produkt. Kan bara rekommendera. Men mycket störigt med ljudet, så stäng dörren till barnens rum 😊
