I took this mouse for its shape similar to the old Logitech G3 that I use for years (to equip another computer), which is one of the few models that Logitech is both ambidextrous and gamer (I'm right handed but I do not like the so-called mouse "ergonomic"). What a disappointment ... mouse too slight (and I do not like too heavy mice, but even there ... qd), loud clicks, cheap plastic, no longer function button mouse ... this is not worth better than a no-name to 10. We are very far from the Logitech G3 I know (except the shape ...).
I put 2 stars becaufe works properly and that its optical sensor has a proper sensitivity, but it is by no means a mouse for gamers.
I have preferred her big sister the G300S, ambidextrous too, less light without a keypad, and with well-placed function buttons.
