Not only on glass the mouse has its merits. Through high-quality materials which feel my opinion is to none. Weight and size are very well matched. For a "normal" big hand neither too big nor too small and especially not too easy. The mouse can be operated with one or two batteries. It is a pity that no Bluetooth option is offered and the Mini Unifying receiver requires a USB space.
Often there is criticism that the mouse buttons after a while no longer correct appeal. I can confirm that, but the problem can be easily fix with a little contact spray.
Since the mouse as it is has no weaknesses I forgive like 5 star.
