Summary: Very, very light usage since we purchased it about two years ago. No more than 400 hours of total usage (in fifteen minute chunks with the unit powered off inbetween) and it is now impossible to use owing to the black and white spots taking up about 40% of the screen. Will not buy again.
Summary: I too purchased a pico pk-201 in 2011. It worked well for aout a year. White spots began to appear on the image. Then they multiplied to the point a third of the image was unreadable. I bought a back up unit but wanted to get the first one fixed so that too could be a back-up. Its still under warranty.... so I just called the company...Optoma told me it indeed was under warranty but I would have to pay for the labor...
Summary: Only used this thing maybe 4 Times, and Last night turned it on and White spots all over the screen from a Bad Cmd chip as I googled the problem that so many are having. Optoma should refund all our money or give us a free corrected Projector!! I am truly disappointed, on this huge waste of money, and in Optoma! With this experience I would Never buy another Optoma product again, nor encourage anyone else to do so.
Summary: very disappointed in this product. Image at max. size is not clear or clean. Returned it 24 hours after I received it. Required a special patch cord to use with the Macbook Pro. No instructions come with the device and customer support was terrible. Keep shopping...!
Summary: I Bought this projector in Nov. 2010, During the watching of a movie I noted white pixels. More and more are developing over time rendering the projector useless. I used the projector only for watching few movies and is not even near it's 20.000h lifetime as stated on the brochure. If anyone knows how to remove these, Where I could send the unit in the USA for warranty. please let me know.
A lot of dead pixels after 1.5 years. (black and white)
20 January 2012
Summary: I Bought this projector in 2010, here is what happend over a year later: During the watching of a movie I noted a few white pixels. After further examination I also noted a lot of black pixels. These pixels stay black or white independent of the source. More and more are developing over time rendering the projector useless. The projector is only used for watching movies in the bedroom and is not even near it's 20.000h lifetime as stated on the website/brochure.
Summary: The projector was nice while it lasted. I've only had this thing for a year and the screen is starting to look like a star field. No it is not dust, as I have cleaned out the projector thinking the same thing. Apparently it is the chip. I only discovered this after Googling "white spots pk201." I do not recomend this product.
Summary: I was so excited when finally my PK201 arrived. I read the manuals before actually used it, charged it, connected to my laptop and watched one 20-min tv series. At the end of the series, I realized that white spots started to appear at the bottom of my screen. Now these white spots have multiplied and black spots are also appearing and multiplying themselves. All in a span of 1 hour since my first usage!!!
Summary: It's very simple: with virtually no illumination, it will not project in anything other than a pitch black room. It's a great form factor, and I was probably hoping for more than such a tiny thing could deliver. Returning it to Amazon was a breeze. Who knows? maybe some day a tiny pocket projector will be able to deliver. Not yet...
Summary: When I bought it upper corner of the image was blurry. I should have returned it. I had a project so I had to keep it. Now there are bunch of white spots on the projected image. Optoma Technical service does not reply inquiries. Waste of 280 dollars...
