I find this mouse very well. The scan on my desk working properly and the mouse is also comfortable to hold. The mouse wheel is the only snag with this product because it has a relatively large margin. One can thus "wiggle" properly without that it triggers a function. In addition, I had problems installing the software, because I just could not be downloaded from the home page (page not found). I then wrote to the Logitech Support and get this link in a short time: [...] Thus, this problem was solved then. I would recommend this product anyway without restrictions.
