The cheapest UST projector I have seen. Yes, it's only 1080p but that's already a good price for a normal front projection let along UST.
Brightness is 800 ANSI lumen, should be adequate for any environment with low ambient light considering its short throw, but better if fully dark. DLP should have better contrast than LCD.
800 lumens is very low for a regular throw projector. For a UST it is even worse.
