As per title. I really like this mouse, and have bought the MK710 set multiple times over the last 10 years (at least 3?). I've just had another mouse fail - more likely through my careless use as it's the one I travel around with, not an issue with the mouse. I'm trying to see if there's another option for a full-sized, comfortable mouse before I spring for another MK710 (because the set remains cheaper than buying the mouse alone).
