This mouse worked fine when I got it in May, had no problems, operated normally and such. I don't know why but the tracking speeds are very erroneous and throws the cursor around the screen. The worst thing is the accuracy and it lags a ton on any surface, it is frustrating to use the mouse now. This started happening 2 weeks ago, it's the worst. Don't buy a cheap mouse, you will get bad performance.
Output:
Negative Review
