GREAT, little, convenient, optical mouse!!!!

this is an exteremely useful mouse to travel ot just use at your desk while your working on your laptop. I really like that it's sensitive, nice and small, conforms to well to your hane, easy to change the battery, long battery life, scroll ring in the middle of the two buttons, and the thing I LOVE about this mouse is how the receiver that hooks into the laptop USB port, conveniently snaps INTO the mouse. That was very important for me, and should be for you, because if you lose that....the mouse is unusable..think about that. hehe. so I HIGHLY recommend this product, it's wonderful. the only bad thing I have to speak of is that sometimes on certain textured tables it doesn't work to full potential; it's not that bad though.
