I bought this mouse 4 years ago for use with my laptop. It is really small, and very compact. The usb cable is very thin, and retractable.This mouse was used CONSTANTLY for 4 years, still works great. It has been thrown around in my backpack or my laptop case hundreds of times.The only problem was that the 'slippery' plastic corner things wore out but i think thats normal...i still use it!The mouse wheels still works great
