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. Looking for information I saw it happens very often and there is no solution. The price to fix is the same of a new one. I don`t intend to buy Optoma anymore...
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: 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: Stay away from this model. I got mine back in late October, 2011 and it hasn't even lasted four months. It turns on long enough to display the Optoma splash screen and then shuts down. I've been using it approximately two~four hours per day, but that can't possibly equal 20,000 hours (unless they're rounding up from roughly 200). I attempted to get service from Optoma but after five days have yet to hear from them.
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. Optoma has not responded to our request for warranty support, and the "Return Merchandise Authorization" form on their warranty service website is a dead link.
Summary: My Original review: ---Very much proportionate for cost, value and performance - lets cut the crap I had a list of portable LED projectors <500 and preference <300 and list is 1. Optoma PT100 2. Optoma PK301 3. Benq Joybee (competitor) 4. Acer K11 (no audio out with HDMI input - poor design) 5. LG201 (its best of today, but not @my budget its 500) I am not going to talk about options 4 and 5.
