Although the mouse has good sliding properties, is easy and is relatively well in hand, but what annoys me the most, and why I even 2 stars awarded - each click of a mouse button requires a relatively large force, is a bit noisy and the case creaks Here also, which is quite annoying in the long run.
I do not know whether this is a Monday device or not, I do not guess more. I've thought Try Logitech out, got the much more favorable Logitech bought M90 (about 6), and which is really worlds better - no creaking, loose smoother click and likely to dissipate even higher, but unfortunately a little smaller and therefore something unsuitable for larger hands.
