My 17 month old recently walked in my computer room, climbed up on the chair and was moving the mouse around. As I walked in, he was about to investigate the red shiny cool looking light under the item he was moving. I'm so glad I walked in when I did, if he would have looked directly at the beam, he could have damaged his young eyes. Because he's such a climber, I thought maybe getting a regular ball mouse might be better. Are there any highly recommended non-optical/non-laser mcie still available? I currently have an Logitech MX510.
