The projector is large and heavy, which is known, is evident from the specs. Clean, solid construction, installation simple, intuitive menu navigation, image reproduction is excellent. Everything as you would expect from Panasonic and as it is promised in the product description. Why then a review "do not like it"? It is the operating noise of the fan. When operating in ECO mode in a darkened room, the noise was even after extensive fine tuning at + - 30 decibels. This is in my view for a home theater projector, be reproduced on the not only loud action movies, just too loud. Therefore had to return to the projector. Unfortunately Specs Panasonic contain any information for operating noise, so could not check this point before my purchase decision.
