Summary: Efficient and responsive mouse. The wheel is fairly smooth too. It plugged into the Mac immediately with no hassle. I wanted a USB to save on batteries for my wireless Magic Mouse which is fairly heavy.
Summary: I got this to replace my cordless mouse because I was fed up of charging batteries every couple of weeks. It's simple, comfortable and works well with my iMac. The scroll wheel is a little soft but I soon got used to it. Great mouse for the price.
