Query: Microsoft Wireless Optical Mouse -Mood Ring

I have had this mouse for several years now.The mouse is stylish and I love the blue and grey color of it. I'm on the net a lot and have not had to change my mouse batteries out for long periods of time; which is great!This is the best mouse I've ever used!Peg Schindler
