Query: Great projector

This arrived in less than 1 week! It is incredibly quiet. I can't believe some reviews say it interfers with the movie. We are beginners in home theater and not tech savy, but this makes us looks like a professional theater!. Even with DVD's that are not HD it looks great. We run it on low lamp and it is plenty bright. We are so glad we got this one.
