The mousepad looks great, the gel pad is comfortable and it may perhaps be that the surface has low power consumption (no idea if this is true). The relatively high weight and the bottom made of rubber (or similar material) the mouse pad is also firmly and safely without slipping on the desk.
But after only a short time (4-6 weeks), the reference is released from the gel pad, which I am constantly come hand in the sticky gel. I've had to go back the mouse pad. For the high price, the processing is wrong, there must rectify 3m.
