[PRO] + All-round pleasant surface + Relatively easy + Is very good in the hand and both "palm grip" and "finger tip grip" + The primary buttons go very light (but defined), which is new to me, but I think it's great! +++ Precision ... I notice improvement even on the desktop compared to an older gaming mouse.
Could be better The mouse wheel click is quite firm, could ideally be a tad lighter The cable could be something lighter and more flexible (but then Logitech would have more cases of warranty)
A matter of taste: The wheel has very clear clicks, the item selection is but perfect
