The top left-handed

Excellent product! I already had the version for right-handed I was fine. Its shape allows a good grip of the mouse.
With this version for left is that pleasure, with ergonomics and more and buttons accessible on the side of the thumb.
I'm not expert on mouse me but perfectly adequate for gaming or surfing, it has perhaps not a 10aine buttons but what counts is that it is comfortable to hold.

I put 5 stars because it must be the only gamer mouse left and it's a real pleasure to play with.
