I am Using it since 1 year and I hadnt any issues with this wireless mouse and I tell u that I hadnt change the battery of the mouse as I do not use regularly so it is still working . The performance is awesome and there is no issue while paring with the my laptop . Let me clear that this mouse is only for work or regular use it is not for gamers as dpi is low because it is not a gaming mouse . Overall performance of the mouse is good . And the build quality is very good as I have drop my mouse one time but it didnt breaked . S o I recommend if you are thinking to buy a wireless mouse you can purchase it. And the hand grip is also good it fits in hand perfectly .
