As mentioned above by dersquisher, these projectors have a very low native resolution. All of them appear to be 640x480. If you are looking for home theatre, this is NOT NOT NOT what you want.
However, the light output is decent and the lamps are LED. I am surprised to find an LED projector with over 1000 lumens for this price (more understandable with 640x480). If you, like me, are interested in a cheap, mobile-ish, cheap, cheap projector then this is a great option.
I do not need high resolution for my type of projections. Most of my audience will not be close enough to get much resolution out of it anyway. It is nice that I can still connect the input of my laptop and the projector can use it.
I worry about taking my optoma HD180 (good for home theatre) around for educational presentations, so this is a great option. On top of that the LED is the only reason I am getting it. Something physically in the projector will fail before the lamp. No expensive bulbs, and for something mobile it is great not having to wait 20 minutes after use to be able to move the projector for fear of damaging the bulb.
This, like many products on Woot, has a more focused use and niche than just general use. Think what you want the projector for, this might still be what you are wanting.
I shall update my information after getting the one I ordered with information from hands on use.
tl;dr: NOT a home theatre option, good if you need a cheap and mobile option for presentations that do not require high resolution. LED bulb with decent lumen output at low cost is the reason to consider it.
