Classroom friendly supplies

I don't actually know much of anything about this pencil sharpener, but they claim to the the best thing ever for teachers. And I read a handful of the reviews and they were all good. And from the video I watched, it looks pretty neat. Plus, they're doing a give away. And who doesn't like free stuff?! So, if I win it, I'll be sure to let you know how great it really is. :)
