A clear case of 5 Stars! The mouse fits comfortably in your hand and is very precise. I currently use even without a mouse pad on my desk. The USB cable is long enough to route it through my wild desk structure behind your back to the USB port of my computer. Thanks scroll wheel, which can be configured by the downloaded software from the Logitech website "SetPoint", can be an excellent website scroll. The left and right mMusklick is tired and rastend.Besonders well when working with graphics editing. I can only say that this is one of the best devices I've ever bought.
