Well, there are mice with more defined keystroke or better haptics - the main thing but it works. And it does. However, worse is the wobbling - the thing is just not quiet! Moreover, the mouse is not necessarily ergonomic - in any case I had at the beginning some difficulties getting used to the hand position. Maybe's but also my hands ...
Summary: Technically, feel and ergonomics improvement. Okay for the price if you get along with.
