BurnOutPC.com has posted their review on the XTracPads Ripper
The Ripper series is available in three different sizes, from this size, to one larger and the XXL. Ranging from 13 dollars to 25 dollars. If you know that you are not going to use all that space that the XXL has to offer than you should pick a smaller mat. Their all from the same material and they all glide just as smooth. It's again a matter of preference and price. Overall a nice mouse mat.XTracPads Ripper Mousemat Review
