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

This device works well and it was easy to set up. I have already used it several times and it makes presentations a breeze!As someone else pointed out the buttons are not intuitive for forward and reverse on presentations. This was not a deal breaker for me. I simply turned the ring around so that the laser pointer (which I do not use) is pointing into the palm of my hand (see pic). The raised stud on one of the buttons moves the slides forward properly. With the ring reversed, moving the thumb down to the (Now reversed) second button allows you to go back in a more natural motion. Hard to describe but it works.As someone else mentioned, the wireless dongle when not in use passes into the ring hole, so if you are using it with Bluetooth, leave the dongle at home or leave it in the pouch this thing comes with.
