So for the price, you get really a top product. I had not expected so high rather "cheap" materials and workmanship, but is not so. The mouse fits comfortably in your hand and is very well made. Connect the work on a Win7 HP notebook without problems. It remains to mention the small USB plug, it does not bother. You can him leave plugged into your notebook all the time. Because he just is not in the way other male, the assume the size of a USB stick. Been working for several weeks with your mouse it works great on a variety of terrains.
