Over the years , I have bought many mice, but this one is definitely the best for all round use. The action of the scroll wheel is just right and the screen magnifier comes in very handy for things that are a bit too small. Don't forget the side to side option of the scroll wheel as this means if you need to scroll sideways, you can without lifting a finger.
The first one of these I had lasted about two years and the scroll wheel packed up, I think two years use for a mouse is Excellent as others I have paid good money for don't feel as good or work as well. My new one is just as good as the first .Highly recommended.
