A:Answer Hi, I bought my mouse off of amazon but am having the same problem. I've had the mouse for about a month now and have just been using it wired, but when playing highly reactive games the wire can add some drag onto the mouse and add onto the 66 grams the mouse really is. I'm asking if you have figured out the issue or if you had to buy another dongle or even another mouse. I've been thinkin about buying another one just to see if that one works right. Kinda fed up though, please and thank you.
