I used it almost 3yrs until I knocked it off the desk & the battery spring come out inside the mouse. Overall Review: I highly recomend this mouse. It is small for those that have small hands, every comfortable to use. I didn't have to change battery to well over a yrs use. It has on/off switch & only uses 1 AA battery & it comes with a supplied AA battery & nano usb receiver. Pros: Bought this mouse in 2014, I knocked it off the desk in 2017 & the battery spring came out inside the mouse, couldn't fix.I was looking to buy this mouse again.
