I will admit this is my first time buying a projector. However I could not have been more pleased. It was really easy to set up and use. Plugged it in, set it down, put in a CD and focused. I have used it in doors and out doors for movies and games. I am the envy of my neighborhood. It has an optical out for surround sound, so you can plug it into your home audio system or buy a set of 5.1 computer surround sound speakers with optical input. I spent 100.00 bucks for those. I have not received the screen yet it takes some time to get. However even on a wall or the side of the house, the picture is better than I would have expected. I have not tried watching a high Def sports game on it yet. (that is next) It has a ton of features for watching movies. I won?t make this hugely long but I am very glad I bought this. I have had it for over a week and watched probably 8 movies on it and games. Every one I have showed this to has been very impressed. The two things I like best are the following. Really short throw distance. I have it in my bedroom 6 1/2 feet from my wall and I get a picture over 100? in diameter. Next we tried it on the side of a building and had to pull it back about 30 feet but got a picture size of over 300? in diameter and the pictured still looked great. Everyone who drove by in the parking lot kept stopping by it was great. Two thumbs up!!!
