3M 9100 Overhead Projector

Great buy for the price. Does exactly what I was needing it to do. Secondary bulb got busted in shipping, but item was well packed. Carriers get a little rough sometimes.

This is an okay piece of equipment. However, the on/off switch does not work. I have to squeeze a folded piece of paper in the crack between the on/off switch and cabinet to keep it on. It is compact, which is nice.

On May 12, 2010, I ordered a used 3M Model 9100 overhead projector from Oneil Imports in Carrollton, Tx. - I was so excited and pleased when it was actually delivered On May 17, 2010. We took it up to the church (for which it was ordered), to try it out - and when we plugged it in - and turned it on - were delighted to see it turn on and showed a large lighted square on the wall for our overheads. Then withing seconds of turning it on, it quit running. We tried several times to get it to stay running. It would not. - I believe this to be a defective piece of equipment - I would like a total refund of cost and shipping.This company is not rated by the BBB. And to the BBB's knowledge this business had closed their doors - not so. I would not recommend ordering anything from this business.I tried calling this company - two different phone numbers - both had been disconnected.

The product arrived on time and well packaged. Plus, it had an operable light bulb which I wasn't expecting. My only dissatisfaction is that it is not operable at this time because the lens is warped. If I want the transparency to be visible, I have to hover it about two inches above the glass. This makes the projector unusable until I replace the lens. :-(

It is in perfect condition. Didn't think I'd find another one like the one I had. Don't know what i'll do without it.

I purchased a used 3M 9100 for my wife for her craft projects. The projector arrived with a significantly damaged projector head and a twisted and bent projector arm. Surprisingly, the lenses and glass table were intact. Following contact through Amazon, the seller (realfinds) offered to send a replacement unit however I requested just the arm and head and replaced the damaged parts myself (just one screw and a bolt to remove the arm assembly). As for the 3M 9100 - Pluses: The overhead projector works well for our purposes, sturdy base unit and arm, arm pivots for storage, easy bulb changes, focus and adjustments are ok. Minuses: bulky to store, even with the folding arm, no carrying handle, lens mount rather flimsy, hard to access lens for cleaning, middle grade fit and finish. A 4 star product.

I understand these are "gently" used classroom projectors, but it came filthy and the lens was cracked. It does not adjust very well for smaller projects. If you have a large project, it would be great. I did get ahold of the seller who did send me two lenses. One was used and scratched and the other thicker so I was unsure it fit. Did not want to break the lens. The seller is very good at communication, but like I said...I should never had paid $100 for this junky projector!

Very unhappy when I received my overhead projector the Fresnel lens was cracked I half and the focusing lens in the head was jammed inside the head. None of this was written in the description of the product. I will never order anything from this company again. I didn't no they just wanted to steal my money.
