I bought this mouse to replace the horrible mouse 2 euros provided to my work too much twisting of the wrist, fingers curled, no slides. I have read forums and other comparative until it fell upon this model that I bought in 2011. Since then, I use it every day at work, it is still like new. And my wrist, my fingers and my arms tell me thank you, I do not have any pain in the right upper body. The supplied software allows you to save several different configurations for customization buttons, a player may find that this mouse is too limited (although ...), but personally it does not bother me at all.
I just love this mouse that I bought one for my home (and ditto, it is like new since 2011).
