I bought many years ago, this mouse rather by random selection and since then I can with any other mouse stop working really, gaming etc ... also have a 70-euro COUNCIL mouse for gaming, which I use since only for my second computer ^^ I realize that this is very dependent on type, but good for me this mouse really extremely good. It is light (which basically does not speak for the processing etc), thus it slides quasi effortlessly across the table (using no mouse pad, is superfluous here) and the buttons or the scroll wheel feel great. It also seems to me pretty precise before, although my other mouse would have to be technically better. Design Technically I find them now not as overwhelming, but it feels damn good. For me one of the best investments. Absolutely sufficient durability, they've been around for about 3 years in continuous use! ^^
