Summary: I do not own one of these projectors. But I think if one purchases this you would need to know the life of the projector bulb.HD700X Bulb - Optoma Projector Lamp HD700X Optoma Bulb Replacement without cage assembly HD700X Optoma Bulb Replacement Projector Bulb Replacement 180 watt Projection Bulb List Price: $337.61 If the life of the bulb is short this is a very expensive purchase!!!!!!
Summary: The good things about this projector were it's excellent image quality and ease to set up. The bad: it was reasonably noisy, had a very narrow range you could have it away from the screen, and it failed after not many hours. It developed black vertical lines down the screen, so after trying different power supplies, it was into the bin with it.
Summary: After much research I chose this superb projector. Small, neat, quite easy to use with a great picture quality. No rainbow effects, no fan hum and no fuss of any sort. Will project from any device I care to think of. At the moment it's running off a cheap Asda HDMI DVD with old computer speakers and it's wonderful. Clear picture even in normal daylight. Draw the curtains put on Lord of the Rings and the world becomes a better place. Great product at a good price.
