Review on NORWII N26 Presentation Laser Pointer for Cats and Dogs - Wireless Presenter Remote PowerPoint Clicker, 330FT Range, 2.4GHz Presentation Pointer for Mac, Laptop, Computer - PPT Clicker for Enhanced Presentations by Jeff Sorensen

I haven't tried it on foils that I don't need, but I'm always annoyed when such little things end up in drawstring bags! It just makes owning the item that much more fun! As you can see from the picture, the red dot backlight is bright and sharp, which makes presenting much easier! There is also a switch, so if you put it away and accidentally put something heavy on it, it won't turn on the light for a long time and will drain the battery! Unfortunately, the ones I've used before don't have this feature, so I highly recommend this purchase!
