I use the mouse with a MacBook Pro Retina and am completely satisfied. The mouse had to be synchronized only once and now it works perfectly every time. It connects up to now always without problems.
The fit I find very pleasant. Of course, the mouse is slightly smaller than a standard computer mouse, but as it is (at least for me) intended for mobile use that fits perfectly.
For people with large hands, the mouse could however, I may be a bit too small imagine.
The buttons and the scroll wheel are well positioned in my opinion.
One criticism is the Macbook Unfortunately, that can not be the side buttons programmed. But that is as I said earlier on MacBook, not to the mouse!
