After 3 weeks of use I can say that it is a very nice mouse to use at least for my use (desktop PCs, digital home cinema, photography software). For button I find similar to other mid-range Logitech mouse as the M705. The touchpad request an adjustment period but I find it quite nice (small prerequisites: not having sweaty hands but then it is valid for all touch surfaces ...). By cons must not delude ourselves, a knob will go much faster, it's not a mouse for the impatient who want to change their habits and of course this is not done for gamers .... I wanted to try it with the idea of selling it if it does not suit me, and although I decided to keep it because I find nickel for my use.
