They use egregious in the "extraordinary" sense, meaning the battery life's great. Once it does need charging, it can still be used via the cable during charging. I have to agree, specifically mice have been the least painful Bluetooth experience for me, with a Microsoft. Annoying part is that it changes MAC address when pairing, so regularly using it for more than one computer is a frustration but that's nothing compared to the constant interruptions I've had with keyboards and codec issues with headsets.
