Summary: Purchased in January 2012 from Amazon, and paid 587.99. Item description is clear that it does not have an audio output, so I knew this when I bought it. Over this long-term use, the main hassle I've had with the device is a lack of an audio output jack when I'm using the HDMI input. An earphone jack would be perfect for this. I knew it didn't have it, but this missing element became a bigger hassle than I had originally envisioned.
Summary: I spent a lot of time tossing between this and the AAXA version. In the end, I picked this one as it was clearly 500 lumens. The AAXA, I have since discovered, is 450 Lumen (AAXA aren't very good at communicating it would seem), had I known at the time I would have probably bought that one. 4 stars because I would have liked this to have 3D (although 3D scares me). The latest version does have 3D though, so make sure you get that one.
Summary: I've wanted a projector for a while and finally decided to splurge on one. After finally narrowing it down to either the Epson EX 5210, Viewsonic PJD 5133, and this I decided to go with the ML500. Here's why Lamp life: The epson and viewsonic were rated 4000 - 6000 hours with each replacement bulb running approx $200(USD). If you were to use it for 7hrs per day everyday the lamps would need to be replaced every two years.
Summary: If you use this projector as a lightweight, portable and mobile projector, I think you will be pleasantly surprised. My typical audience would be 4-5 people in a lit conference room, projected on a wall. I purchased this primarily because it was an LED light source. I have had other projectors bulbs break at inopportune times. I wanted to also make sure that the projector had an internal power supply.
Functional. Good video quality. Update on 1/22/2013
RPP "RPP", Amazon
29 June 2012
Summary: Length:: 3:00 Mins --Start of update on 1/22/2013 For the past few months, i have noticed that the video randomly goes blank, it displays "searching..." and the video comes back again. At first i thought it was not the projector. Later, i contacted customer rep and they said it's a HDMI bug (i should use shorter cables). But, i see the problem continues with all types of HDMI and VGA cables with different sources (laptop & cable box).
Summary: update 8-2-2012 over 1200 hours and all is well. (still shuts down every 120 hours like clockwork) previously we have had multiple pjs, our last one was a lg hs 201. this is a 5 star item...except. shuts off exactly every 120 hours and the power light isnt even lit, just unplug for a min then replug. this has happened to us twice in the 3 weeks we have had it.
Summary: Personal Experience after few hours i had fan failure why? pc fans on my pc run 24/7 and have tons of dust and never any problems "bad fan design perhaps?" Other then fan failure the features and connectivity are awesome, super bright for led version and great picture quality.
Summary: Instead of purchasing a large LCD, I opted for the portability and convenience of a projector. Like the other new LED projectors on the market, there are significant limitations to this unit, such as the lack of brightness and no optical zoom or lens-shift. Nonetheless, if you have a compatible viewing space (right throw distance, ambient lightning, etc.), and can accept the quirks of projectors, this unit makes a suitable replacement for a conventional display.
