Summary: I bought the Logitech Wireless Mouse first for it's price value. The second reason why I bought it was because of it's compact size. Once I had received the mouse and put it to work... I noticed right away it was the perfect purchase. It gets the job done and is very responsive to every click. If you are looking for a wireless mouse I recommend this one.
Summary: Not the best wireless mouse in the market BUT considering the price I have to say this is the Best Buy Product... It's design is simple (and yet comfy, contoured shape), light weight, very responsive, and to my surprise no lag at all even when playing games. The nano receiver is also a plus feature Cons The bottom cover (for the battery and receiver) is not very tight fit. No light indicator for battery life Original battery that comes with the mouse died within 2 days.
Summary: This is a bit larger than my old laptop mouse but it is much more reliable. I love the short, stubby usb receiver unit. The one I had before was like a regular usb drive in size and I was always bumping it on things and bending it...finally to the point it ceased to function. This mouse is still small enough to fit into my mouse pouch and I can leave the receiver plugged into the laptop when I transport the laptop in my laptop backpack!
