I recently purchased a logitech performance MX and i'm somewhat reluctant to keep it because I have been getting bad latency issues with it. I purchased it on eBay and it stated that it did not come with the original rechargeable battery. The problem occurs when I leave the mouse alone for a few seconds and I go back to it, the cursor just stays there for 2-5 seconds then jumps on the screen. However, this problem does not occur when I have it plugged into the USB charger (basically acting as a wired mouse). What should I do? Do I return the mice on ebay? Do I use it wired? Do I get a new battery?
