Review: Extremely accurate high click rate and super durable - 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.
Review: GD - Its ez to use and i like the clicks its also durable it looks good and customizable was a bit non beginner friendly to set up
