I had a corded optical mouse. I googled about this mouse for along time b4 buying from Amazon. Amazon had the best price and the best price for the shipping rate,FREE. This mouse is amazing to work with. Now it is heavy it that wound bother you, but I like the heavy feel. I bought it to use with gaming and it works great with HalfLife2. Do not pay retail for it, in fact do not pay retail for anything electronic. So far I have used the mouse for 2 weeks w/o a re-charge. Usually at that time I will re-charge anyway, but the charge light indicator still has 2 lights on. I have not found any negatives for this devise. Buy with confidence.
Output:
Positive Review
