I ll be honest, I finally have the project perfectly aligned to the screen and I am not going to look for the serial number... so this will not be a verified review.
I purchased the EH 300 last week and this is my first projector and therefore I have nothing to compare it to. I will say that I was very nervous about purchasing a projector because I had heard that the quality was not as good as a TV. The EH300 has dispelled any preconceptions I may of had before. The quality is incredible, stunning actually. I just watched Avatar on a 110' screen and I was completely blown away. I won't pretend to say the contrast was this or that the lumens were that, I don't know anything about stuff like that. What I do know is that I am personally very satisfied with my purchase.
I would be happy to answer what questions I could about this product but it will not be in a very technical way.
