I know it says it's a large mouse mat, but this is taking the... biscuit. It's flipping enormous!
Without measuring it, it's about 50 x 40CM's (19.5 x 16 inches). It dwarfs a standard mouse mat. I think I may need to trim it down. At least I can have one half at work and the other half at home.
On the plus side, it's a very good surface, it feels nice; and it doesn't slide around on the desk. The main reason I got it was because it said that it was nonslip not because of its enormous size.
If it were smaller, I'd have given it 5 stars.
