Gear Head computer mice do not make efficient use of their batteries, and the sleep mode they feature is faulty. These issues result in frequent deactivation during use. Also, Gear Head mice are heavy and do not respond well on every surface.
Consumers report their Gear Head mice dying within the first few months of use, usually due to electrical shorting or battery failure. This failure also results in battery acid leakage and electrical danger. The persistent battery issues force consumers to spend more on batteries. Gear Head mice also feature a sleep mode to preserve battery life; however, this mode sometimes permanently deactivates the device.
