The media could not be loaded. I bought this for osu and gd. But I didn’t expect it to be this good. It’s very low latency and yeah. If you’re on a budget I would recommend getting this. It’s also very customizable. Changing colors photos, you name it

This is a great price for a device like this and my son loves it. I find the clicking a bit much but I guess that is the point.

    • Cheaply made but works good.
Color: white
Bought for OSU! Works very well. However it's extremely loud due to having zero sound dampening material. I was even put off from using it for awhile cause of this. Placing it on a mousepad reduced the sound significantly.

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.

    • MY GAMERS LOVE IT!
Color: white
Both of my boys have these and love them. Surprisingly, for as long as they’ve been using them and as much of a beating as it sounds like the thing is getting during hours of gaming, it has held up for over a year and counting! No complaints- great product!
