Pretty nice mouse ideal to accompany a laptop. Then I find personally a little too small and autonomy is not up to the logitech mouse without wire (batteries unleashed after one year). Moreover, it deserves to be sold a little cheaper because we did better today level quality / price ratio. But it's still a nice mouse to use with everything one would expect from a modern mice: previous / next buttons on the edge, change DPI on the fly and anti-slip area under the thumb. 3 stars so for me, perfect for those seeking a little mouse with good amenities and changes of Logitech that is seen everywhere.
