For me at least (I may have just gotten unlucky) it had some serious problems with how well it connected to its reciever. Even at very close ranges it would frequently drop connection and become unresponsive for a short period. This made it teduous and somewhat frustrating to use for normal applications, and impossible to use for many games. On the plus side it is decently comfortable to hold and the quiet click is farily noiseless (if the click registers through the aforementioned issue)
I may have just gotten unlucky but will leave this as a warning that there are definitely bad versions of this product in stock.
