Bests & Worsts Reviews from Amazon

Started out pretty nice but after 3.5 weeks the mouse no longer tracks properly. Even after charging all night, after about 3 minutes of use the cursor refuses to respond to the mouse movements. Update: The vendor keeps sending me emails asking me to delete this review for $30- I'm guessing they don't want me to write this on the review but I've told them no three times now and they just sent another one. I've told them that it's unethical. I've told them its completely against the spirit of reviews in the first place. And there's another one in my inbox. *sigh* I guess I just forward another one to the Customer Service Department of AMazon.
