Input:
I work at a computer all day and my arm started to stiffen up from reaching to the same position all day, so I decided to get a cordless mouse that I could set anywhere and not have to move as much. Loved it so much I bought one for home! I love being able to put it on top of the desk, on top of the stacks of papers in front of me, all the way to my right, on my keyboard tray or hold it in my lap when my arm gets really tired. It goes a LONG way to prevent pain. The other reviewers are correct in that this is best for desktop computers, and I wouldn't recommend it for laptops based on the receiver cord.
