The black one is my new one, the blue the old.
The ripper xl from xtrac is a cloth topped pad like most normal foam/cloth mousepads, but fricking huge. 1 foot x 1.5 foot (14×18 inches)
The blue one is really thin and covered with bumpy plastic. I used the heck out of it, to the point the texture was gone. This made it collect mouse boogers on the feet. Figuring the cloth should keep it at bay.
review of the $15 mousepad? Naw, it is a mousepad, but it is fricking huge.
