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.

    • Wonderful product - slow shipping.
Color: white
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 gaming device
Color: white
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.

    • Very good!
Color: black
I used the Sayo device for Geometry Dash, and it works extremely well! I got the settings that worked well for me, but at first, I had to recalibrate it since the key automatically spammed the first button, which was really easy to do. It comes with black keys on it and a set of white keys if you want to change it! It was small and easy to plug in, and I love how it has a screen, and you can put custom videos or whatever on it! I bought the black Sayo device and it went well with my setup! ... show more

The product feels high quality. The switches are really good and responsive. If you buy this product make sure you callibrate it with the inbuilt callibration tools.
