content: This mouse is nice and comfortable, the scroll wheel is smooth and thats about all that is good. The mouse falls asleep like the other reviewers said and it is extremely annoying to try to get it to wake up every five seconds. I just bought a Wireless Logitech mouse for my laptop and have tried my friends Logitech mouse and they are both smooth and dont fall asleep. You move it and they move right away. With this IBM you have to click and click and wait then it decides to wake up. Horrible.
