Title: Very Useful
Review: Well, let's start by saying that it has a lot of functions that you can use, it has a button in the middle which you can use to quickly access to diverse things as Internet, you can personalize the buttons and that works perfectly, quite useful I may say.The only thing: DON'T EVER LOSE THE CD THAT COMES WITH IT because if you lose it and you change your machine or you format it and then connect the mice without installing the software then it will work as a simple mice which ends up being very sad (I lost the CD)But I'd definitely recommend this mice, it's very good :)
