Hey guys, just wanted to say Hi and this is my first post on the forum. I have a Logitech MX Duo that I bought about 1 month ago. I play counter-strike and my mouse sensitivity is usually 1. After some play time the mouse becomes slow and unsensitive and I have to turn up the sensitivity to 3. I'm wondering if this is a problem with the mouse or if the battery charge has anything to do with it. Thanks
