Overhead Projector reviewAugust 25, 2008 The overhead projector was exactly as advertised. It was in like-new condition, although it had been used. The only part that showed any use at all was the reels for rolls of transparancy material, which I do not use anyway. All else was clean and scratch/dent free. Thanks for making this product available.
Good basic projector for the moneyJanuary 11, 2007 6 out of 19 found this review helpful
We purchased several of these for our church several months ago. They are basic, no-frill units but very serviceable for the average classroom. The closed head design means that mirrors don't go out of alignment. Other more expensive projectors have built in "on-the-fly" lamp changers but for occasional use this is a fine option.
