Summary: Fantastic mouse. The track wheel is so smooth and I like the magnifier (it comes in very handy at work). You can program the buttons to do many things, but I like that I can use one as a "back" button for my web browser. Good value, too.
Summary: Have had this mouse for a bout 1.5 years and it works great. Mainly use it for gaming. Battery life is really good. Can usually go at least 6 months without replacing batteries. One of the drawbacks is the software. I uninstalled it. The magnafier just got in the way when playing games.
