This was a good mouse for a few months. It was comfortable to use and I changed batteries only 3 or 4 times.
However, after a few months of regular daily use, the usb connection didn't function any more. I tried everything to alleviate the problem but to no avail. So, used the Bluetooth connection instead for a while longer. Then, the right mouse button became very sensitive and unbearable to use, even at times it did not even register my clicks. As such, I cannot recommend this product.
