    • Extremely accurate high click rate and super durable
Color: black
This thing is amazing. So, so durable. Extremely accurate and provides an extremely high click per second capability. It comes with interchangeable keys, white and black and a cute little colored screen you can customize. One of our sons plays a fast paced rhythm game called Geometry Dash and this sayo device is highly recommended by other gamers. I say that it is durable because it has survived many rage incidents. This kid has destroyed mice, keyboards and even a nice 240 Hz monitor but this Sayo device has weathered all those incidents for nearly 18 months and still works like new. It's a little pricey, but so worth it knowing the quality and durability. ... show more

    • Perfect Size and Super Responsive
Color: black
This keypad is the perfect mini size for GD and doesn’t take up any space. The keys feel light and fast because of the hall effect switches, and the screen actually looks really nice in person. It made my inputs way more reliable when playing harder levels.

Got it a year and a half ago for my now ex bf who uses it to play geometry dash (probably for hours daily). Seems like it still works great!

    • How
Color: black
So uh I bought this yesterday and today I'm writing this because I beat bloodbath today with the Sayo and I don't really have much words because it's my first time using one. What I can say is that the Sayo is VERY responsive and it's a huge improvement from your keyboard if you play gd. About sound, it can be very loud so I recommend changing switches when you can to some better ones that sound better and have the same responsiveness as the ones in the Sayo. And that's it I really like it because it helped me beat Bloodbath ig. ... show more

    • Amazing product, improved my GD skills! The only issue is that the website goes down often.
Color: black
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. ... show more
