Sorry to be brief to the point here, I'm just writing this as a gesture to others so they can have an informed purchase experience the way I usually do based on reviews. So let me just state that this is a great little mouse for the price I paid. I bought this for a Powerbook, I was hesitant at first because the specifics were not clear enough about Mac compatibility but it is. It works wornderfully, specially in tight little spaces or any rough surface. It also matches perfectly to my platinum looking laptop. There were no connection issues, it instantly recognized the new device when plugged to the usb port. Buy it, you won't regret it.
