I bought 4. Shiden, Shiden-Kai, Hayate, and Hien. Ended up enjoying Shiden or Shiden-Kai the most. But the white matched my setup so I use that. My one roommate ended up buying my Shiden-Kai and the other roommate ended up buying my pink Hien. My hayate is my backup/keyboard mat. I really like the smoothness of the Shiden, and have gotten very used to it.
