Summary: I liked this unit very much at first - great picture, simple and easy to set up. But after just 14 months of pretty light use my unit started "flickering". Tough to describe but after about 15 minutes or so of use the colors would start to fade and shift and the picture would frequently flash - it would keep getting worse and worse and after another 5 - 10 minutes or so it was pretty much unusable. Problem got progressively worse.
Summary: This product projects GREAT, and looks GREAT, unfortunately, It hasn't even gone through one bulb yet (I've had it almost 2 years) but it HAS gone through 2 color wheels. Apparently their is a problem with the heat displacement or something, but ya, I had to install a color wheel myself, and now, 4 months later, it is doing the same thing, the part is only 30 dollars, but you have to open it up and do a repair that most people would NOT be able to do themselves.
Summary: I bought 6 projectors and in just under 60 days, 3 of them died. There is a fatal design flaw in this projector related to heat. The color wheel assembly goes crazy and stops working. HORRIBLE. Edit: There is no dust filter on these and apparently if they accumulate enough dust they will refuse to turn on. This is probably a fire prevention feature but how hard is it to include a dust filter???
