Unfortunately, the mouse is very small for large hands like mine (I am about 1.90 m long). It also has, like so many, again this nasty plastic surface that feels so disgusting-mealy. Most recently, she would have liked to be a bit of vertical, the wrist is not quite perfect relieved. But compared to normal mice still a treat. Since there is little competition in the area, I'm still very satisfied with the thing and it would buy again. If you touch the back, you will soon cope with large hands. Another huge plus for people who like me to play with the mouse acceleration have ever made: The keys do not reach all the way down, so that you can raise and settle the mouse, without necessarily inadvertently press a key. The DPI is also to play in order. EDIT: After half a year, the surface feels now no longer so mean to, and I am well used to the smaller size.
