2 adjustable feet and anti-slip, the carpet and the wrist rest can be removed for cleaning is the ideal: quality meets my expectations although I find it a little mat for normal mice. (For a mouse "portable" no worries.) As against the image does not match the product received. The carpet is gray, not black, so, we do not see that there is a small ledge around. And the price charged is 22.70 instead of 21.09 displayed. Either I got an old model (but more expensive ?!), or the product is not up to date.
