Hi I have only had it for a couple of days, but it is about to be returned. I just cannot see that the scroll method is actually usable. It constantly loses the scroll ferature and I need to 'close' and 'reopen' it to get any response at all, and then it is *very* hit or miss and usually scrolls in the opposite direction to what I want. Maybe some will find it usable, but not for me. I have ordered another bluetooth mouse from Amazon (as it happens, also a Microsoft one), but with a real scroll wheel.
