Summary: We purchased this projector because the one we have been using for years is cost prohibited for replacing the bulbs. We were able to purchase this one (the top recommended from team) for less and it has more brightness and power. The replacement lamps are available and not cost prohibitive.
Summary: Several years ago I bought the only video projector I could afford: a 1500 lumens one at about $1500. I always have wanted a brighter one. Now I could afford one. I purchased the BenQ 4000 lumens projector. I am very pleased. It is just as bright as I had hoped! And it is easy to run. I love it. It has made my presentations something I can be proud of, instead of wishing my PowerPoint slides would be brighter for all to see and feel the impact of my presentation.
Summary: Personal Experience We bought a couple of these for VJing, especially outdoor projection, after returning some Sanyo XU-115's that we were very unhappy with. The BenQ SP-820's are amazingly good for the price. Bright, clear image, great for carrying around, very quick to cool down. These are the perfect portable projector for guerrilla-style projection.
Summary: Th jury is still out on the lens of this projector. It doesn't seem as sharp as past projector lenses I've had. The fan shuts off after less than a minute. The projector is still hot. I don't know if this will be a problem for the lamp.
Summary: I needed to show a presentation in a tent in a garden and did not want to darken the tent because it took away from the garden talk. The projector worked brilliantly in this setting and all of our statewide speakers were pleased with the imaging.
Pros: Easy To Set Up, Good Focus, Lightweight, Powerful, Sharp Picture
Summary: Personal Experience There is not better deal on the market for a portable presentation projector. Has way more features than you would expect on a projector this price. Has a few cool features. 1. Switching power supply works with 110v or 220v. 2. Shuts down and cools ready to unplug in about 5 seconds. 3. Looks really pretty (both image and unit) I would have been happy with this unit if I had paid twice as much. But I'm twice as happy since I didn't have to.
Excerpt: Hola a tod@s, a pesar de las horas... no he podido resistirme a escribir una opinión sobre este magnífico proyector... que hoy mismo "he conocido" y me ha dejado bastante impresionada. Se trata de proyector BenQ SP820, con el cual ya no hay necesidad de preocuparnos si no nos dejan una sala oscura, ya que los 4000 Ansi lúmenes generados por el SP820 son tan brillantes que son más que suficientes para que una presentación destaque.
Pros: Calidad, facilidad de uso, características a la última
