Review on Rechargeable USB Presentation Clicker W/ 2.4GHz Wireless Remote - Compatible With Mac, Keynote & Laptops by Danny Thomas

I really like this thing because I am very expressive with my hands. It's there when I need to advance a slide and it's out of the way when I talk with my hands. The device has a funny shape which makes it not as obvious where you are pointing when you use the laser pointer, so get ready to point to the backs of people's heads and at the ceiling a few times before you aim at the screen. Also up and down instead of left and right to advance slides is not very intuitive. The button to advance to the next slide has a bump on it at least.
