  • 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.

  • MY GAMERS LOVE IT!
Color: black
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!

  • Ups your gaming!!
Color: black
This Sayo device came highly recommended so my son wanted to try it. HE LOVES IT! It’s helps with repetitive and quick movements in games. Works great with many different games. Just plug it in and play no set up needed and compatible with any used set up. The keys are now loud either!

  • This is a great device. I use it for video editing

This thing is good Solid I found customizing the keys and screen isn’t extremely intuitive bus it works well

  • 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

  • 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
