Annoying
Problem with this device is, all the buttons are so close together that you keep pushing the wrong button in a dull room during a presentation. I am trying to get used to it but saying sorry to the class for pushing the wrong button isn't working for me. One more week of trying then its going back if it wont get better. Also, every time you turn if off it resets to turn on next time with the mouse feature on.... annoying.
