Summary: This projector was disappointing in the extreme. We bought it because our application required ultra short throw. We own several projectors and this one is by far the poorest performer and least reliable in spit of being considerably more expensive than the others. The lamp lasted less than half the stated duty time. Clouding of the glass occurred for no known reason. It regularly shuts down for over-temperature reasons although its used at normal room temperature.
Pros: The general feature list is attractive: ultra short throw, wide screen, resolution, keystone correction.
Cons: Focus is poor and variable across the image. Light level is low.
Summary: Personal Experience I purchased this projector because my apartment is only about 10' from wall-to-wall. I did not want to settle for a screen that was under 90" diagonal, so this projector with its short-throw capability was ideal! It's also nice that no one has to duck under the beam because it's close to the wall. That is important for playing various games like karaoke and guitar hero on playstation.
