August LP104R Red Laser Pointer Wireless Multimedia Device / Wireless Presenter - Remote PowerPoint presentation with buttons Pages Up / Down - Scope 25m - 2 AAA Batteries Included (Electronics)
Very good article. The Laser is powerful, it is very easy to install (you put the USB key, you open a PowerPoint and just one has to click the buttons to advance or rewind) Just one detail: the USB drive is not exactly like in the ad (no black square above) but this is not important. 5 stars !!
