It's a LED / Laser hybrid so unless they used a substantial amount in the last 2-3 years this projector came out then it should still have quite a lot of life in it
They do list the hours of use normally but that can't be seen with Deal of the Day. I'm going to go with a 6 and hope that has something to do with the hours, not just physical condition. I didn't look at the listings enough prior to this going live. Some had no hours, others had a few hundred. But even then there's a lot of life left. I can't imagine with these being demos/returns that they'd have much on them. People like to buy projectors, use them for a presentation and return them. Sad fact.
If you benefit from the deal, REP the OP!
SlickDeals only has value so long as we all share.
