I chose the Omatsuri version over the others for its vibrant colors (and new year) and I don't regret it. Added color (along with my KB) to my otherwise black desktop covered by my mostly all black computer accessories. No issues with it after six months now. Only wish is that they made a V2 version of this with the 3D look of the clouds to make it really pop.
I can't believe that this thing feels so good for only $30. It is a thicker sturdy feeling mat that doesn't trade build quality for color and design managing to do both. Very happy with my purchase.
