Summary: This is quite honestly a steal. The lamp is outstanding, the form factor is great, and its ease of use is also a positive. The only negatives I got for it is that it doesn't have a HDMI or DVI input, so by that nature it doesn't support 1080p.
Would not recomend for heavy use, internal electronics seem to be fragile.

Summary: Was great in all respects except noise for the first 11 months. In the 12th month the picture rapidly took a nose dive. splotchy color, flashing brightness levels, followed by color to black and white flashing ode to Clockwork Orange eye torture.
Summary: I use this projector in a 3D DLP printer and it works great - DLP projectors project a little bit of UV light in addition to regular light, which means they can cure many 3D printer resin brands (but not all).
Summary: This is a budget projector that I have used for video presentations from my laptop. Pros: very powerful lamp creates a bright image even in strong ambient light; image quality and color is very acceptable.
Summary: When the lights are all out, this little beast is awesome. I've actually stopped using my 46" TV (though that is brighter) because this is more convenient and bigger. I effectively have a 77" in "TV" in my living room now, which is nice.
