Summary: I was hesitant to leave a review as this was my 1st Overstock.com purchase. The only problem with this purchase; it was not a new item. I ordered based on what was listed and pictured on Overstock.com. It showed an original packaged Logitech Mouse which includes the battery.
Summary: Purchased this to replace old wired mouse whose cable was becoming exposed and very happy with the new product. Very easy to use without having to install any drivers from CD ROMs, functions well and responds to movement with ease.
