I have this very mouse, and have for years. It's great because it's comfortable to grip and very light. A lot of mice these days are so heavy I don't know how people can use them for 8-10hrs at a time. Also, it has just enough buttons to be useful without having so many it's annoying (you don't accidentally hit them).
