This wireless mouse is just excellent. I am using it since 1.5 years and have nwver faced any issue with this. The biggest point with the wireless mouse is the battery management. And logitech M185 does this job very well. It has a dedicated switch to cut off the battery power.
This feature is very useful to save the battery. My average battery life is around 1 month. Which is satisfactory to me. I would definitely recommend this product to others.
