I needed a mouse with a nice scroll wheel for my 3D software. (Solidworks, AutoCAD, Maya, Blender, ZBrush) It was the best for me. It is the perfect size. It is small but not too small. I have big hands so finding a laptop mouse that is comfortable is hard. This one fits perfect. I use it quite a bit, I have yet to need to replace the batteries and have had it over a year. It runs off 2 AA batteries.
Buttons feel solid with a nice scroll wheel(w/Click)
