Initially, the mouse worked great, rumspinnende except for minor things like low battery life or from time to time software that left- and right-click reversed spontaneously. That did not bother me so much. However, begins now after two years (after the end of warranty), which glue dissolve under the rubberized surfaces so constantly stick their hands. Much worse is the mouse wheel by, because the rubber is also attached with this glue it to the wheel. A mouse with no scroll function is not fun. So many defects were embarrassing even for a budget mouse!
