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

When I made this purchase, I was hoping that I would have an entirely free hand but the device is too large to allow anything else to really be done with the hand.The device advances slides on arrow closest to the thumb which is probably easier but slightly counter -intuitive.All in all I prefer this to larger hand held slide advancers and the laser pointer is super convenient, but if someone comes up with a refinement that is smaller on the hand .

I would be looking into it.
