This is the best mouse at this price point any one can have . Though there are many more mouse at this price point, which could be better! But this is totally different, I have this mouse since I bought my PC and it havent shown any problem since then . This is quick and responsive though not that comfortable, it works convenient to the aspects a mouse can do! So its a worth buy product at this price point, and its a Microsoft product & their services are very good and convenient .
