Amazing 8000 hz polling rate the reactivity is amazing especially for games like geometry dash/Osu it functions very well and has a volume knob very useful if you have a smaller keyboard without normal sound function keys, its easy to connect and was pretty comparable off the start.

I almost gave this product only 4 stars because in the world of Amazon, this item ships SLOW. Just be prepared for that. As far as actual quality - worth the wait. Exactly what my son was looking for. He now uses it daily. Functions exactly as it should and has enhanced his game play.

Great for geometry dash, super satisfying to fiddle with. I went from nine circles being my hardest to beating denouement and getting 71% on acu. All in one month btw.

ive been using this for a couple months and no issues, ive gotten 100k clicks on the middle key and it still works great. the rapid trigger is super responsive and perfect for gd.

It’s very fun to use, the amount of customization feels amazing, and I think it’s fun how loud the clicking sound is. By far the most responsive controller I’ve ever held. I don’t play osu!, but I do play GD a lot, and the ability to spam and click precisely has improved a lot. It has allowed me to complete my new hardest, MikuMikuMiku. One massive downside is that there is no app you can download. You have to configure its settings on the website, which has gone offline multiple times since I’ve had this device. Unless you’re able to play your games with the default settings (Z, X, and C for the keys), the keybinds reset every time the device is turned off, and you have to reopen the website to restore them.

Got this for my kiddo who plays geometry dash and honestly I'm geeking out on this way harder than he even is. It's so incredible all the different functions it has I haven't even figured it all out yet but this was definitely a solid purchase. It looks and feels really nice too. The size is perfect and there is zero lag. As far as I'm aware it doesn't connect with Bluetooth, as it shouldn't sense Bluetooth is not the kind of thing you want to use if you want to skirt lag. Definitely make sure you have a proper cable though, I do not believe for a half a second that the cable this thing comes with is proper. Make sure you get at least a 5 gig data cable USB-C

12 year old was able to program on his own and is thrilled with performance of this Sayo. He uses it for Geometry Dash game. You can use it with an iPad or laptop. Great tutorial by a British young man who teaches how to program it for iPad usage.

Performs better than expected for the price, customization is easy through their website. A must have for any OSU or GD players
