Summary: I use projectors for art installations, where they need to be on all day. I have used this one for 3 or 4 exhibits in the past few years, each 1 to 2 months long, and in the last one, it kept shut itself of randomly a few times. After a while, the staff got annoyed with troubleshooting it, and that particular artwork was out of commission. This kind of issue would not affect most people, but in my case, it is a reason not to buy more of these or similar models.
Summary: If you are considering this project, first thing to do is to ignore the 5 star reviews. I enjoy my ML500, but it's has too many issues to be a 5 star product. If you decide to go with the ML500, the first thing you want to do after you unbox it is to throw the remote control that it comes with in the trash. Get yourself a logitech controller. The include remote is terrible.
Summary: It just works. I was worried about the 500 Lumens and if it would be bright enough. It is if you don't have every light in the room on. Great little projector. It's a little pricey but I've done research and I think you're getting more out of it than one of the little pocket sized projectors. One thing I don't like is that it will lose the signal if the screen is black for a little while.
Summary: The Optoma ML500 projector is a good buy, compact, light, good resolution and very nice features, too bad that they don't all work...The transfer of PowerPoint presentation from pc to the projector was one feature that I was looking for and made me decide to buy this particular model.
Most Excellent HD Projector - Stars Reduced Due to return

Summary: I have had to retract my review being that I had to return my projector. While it worked it was great. However it now will not display color correctly on any input. I returned the projector to Amazon and received a full refund. (Thanks Amazon) This projector does what it claims and does it well. The brightness is fantastic in all lighting conditions. Even in ECO mode the image is great in a dimmed room.
Excerpt: Bueno, voy a realizar mi pequeño análisis particular sobre este pequeño proyector led de 500 lúmens. Un cacharrete aceptable que tiene como gran ventaja el uso de "lámpara" led, lo cual nos proporcionará un uso muy similar al de cualquier televisor. Como proyector tiene sus cosas buenas y su cosas malas.
Pros: Tecnología led; buena luminosidad, buena calidad de imagen . Pequeño y portable .
Cons: La peor : el menú está más loco que catorce cabras .
