Summary: I had a big one to watch movies on my backyard with friends and I use to take it camping, but it was too big and a hassle until I found this one, it has great quality and it's small, very bight colors. I love it!
Summary: Found it on Ebay! Love it! I needed a projector to teach a class of 15 students. Unfortunately, I travel a lot and needed something compact to avoid all those carry on charges. This was perfect. Best investment. I use it tethered to my computer. The only drawback is no remote. But tethered I don't really miss it.
Summary: I actually bought this product for a gift to a teacher. He absolutely loved it however, by the time he tried to run it at the classroom, the connecting cable between computer and projector didnt function regularly. I want to replace those cables and if Amazon does that, everything is cool with the item. If you need one and dont want to pay too much for that kind of stuff, go with this.
Summary: Some reviews for this product were not 5*, but those reviewers must have had exceptional expectations. If you are pointing it at the sun, it's not going to work. At home with lots of lights it is visible. With moderate light (room = 12' x 15' w/6 x 20W CF bulbs) it is okay to good. In low light it is really good - not as good as newer HDTV, but good, even without a formal screen. For vacation and small group sales presentations, it is a good buy.
Summary: Okay... I have a bias, and I'll admit it. I'm an engineer by trade, and I've worked on the design of Picoprojectors for 3M. So I know what goes into them all the way down at the silicon level. There are several approaches to getting pixels up on a screen using as little power as possible (mostly having to do with how you turn the LED's in the "lamphouse" on and off more quickly than the eye/brain can notice that they're flashing).
