Great speed oriented pad with no obvious downsides.

This pad is one of my favorites in my collection now. I love using it, and its perfect for tracking. I also have a Mio and thats about the same speed. I think I personally prefer the Mio over the Sayo strictly because I like the feedback the Mio gives. However if you are planning on using UHMWPE dots, the Mio blows. Both the Mio and Sayo are the same speed in my experience, and I just got a Koku. The Koku is genuinely just too fast for me. So depending on how I am feeling I think i will reach for the Sayo or Mio. The only con that is relevant to me personally is the base on the Sayo. Because of the weird half silicone half some other material thing they did it doesn't stick that well to my desk, and can slide unless I wipe the pad top to bottom to get air pockets out. When it sticks properly I never need to touch it again. I LOVE this pad in use. It feels very smooth but with a slight hint of texture. If you don't like a lot of texture in your pad, you will like this thing. If you want the feedback from the texture, buy the mio instead.
