Summary: I was a fan of Optoma and I still have 2 regular size projectors working very well. My problem was the Pico, after less than one year of litlle use, suddenly, got white dots invading the image. In a few months it was impossible to use it.
Very limited life span, black spots, no usable picture
15 December 2013
Summary: After it died I researched more details and found that the DLP engine is prone to failure. I looked into replacing it, it is possible but $80-100 to do so. Black spots start to appear with use and finally the picture is so degrade it is not usable. Very disappointed, I do not recommend.
Summary: optic went out of order in 1 mo of use, about four times by two hours each (in four different days)/ The window went spotten with white spots. In the OPTOMA local office theay asked 13 000 rub (about 450 US dollars) to replace the optical system.
Summary: DMD chip will not last. After a little use over a year. The project is a dead weight. White pixels appear after its one year warranty. Optoma suggest replacing the DMD chip. Do not buy at all cost.
Summary: After a couple of months the projector does not project true colors, and the color it does show changes with the orientation of the projector. For the money it cost to begin failing after only a few months is very disappointing.
Summary: We started to notice that some of the pixels in our pk301 projector were dead around the 3rd or 4th time we used it to watch a movie. By the end of the fifth time, the image was filled with dead pixels, and it was hard to even make out subtitles.
Summary: Ever since we got this projector out of the box we've had nothing but trouble. Just getting it to power on takes about 10 minutes of button pushing and connecting and reconnecting before we can coax it to power up. And sometimes it receives the HDMI signal and sometimes it doesn't.
Summary: THe small factor appealed to me while my brain was telling me it's too good to be true. It was the latter. The picture is so faint, you can hardly see it in a dark room. The focus is terrible. I wish they could make unit this small that worked well but I don't think the technology is there yet.
