buy this to function as a home and business projector . we have only use it at home . it be pretty much fool proof ... just plug and play . we have a concrete wall with a ton of texture . the paint color be probably eggshell . it be be really clear . I do not even notice the cinder block line while view the movie . apparently it be make to go on any surface . I do purchase 3 yard of black out fabric -lrb- white drapery lining -rrb- for $ 5\/yd online . if you google\/youtube how to make you own screen , that be what they use . it be 60 '' wide . anyway , I have not use that yet , but I suspect it will be really good since this projector do great on we textured wall . it do not get hot and you do not have to -lrb- at least I do not see that anywhere in the instruction -rrb- wait for it to cool down before turn it off . the case be not great ... it be just a neoprene or something similar that you have to slide in sideways vs. just drop it in from the top , but as long as you have a safe place to store it , it do not really matter . the sound be good for use in we very large open ceiling room , but I have it about 2\/3 of the way up and it be not extremely loud . we have very small child , so it be not blast as I know many people like it . so , if you be plan on use it outside , and you like it really loud , you might consider add some extra umph . oh ... and some people mention this , but it be at least decent with all the light on ... and on another night in the late afternoon ... before the sun go down it do fine . of course , nothing like have all the light off . it be a real pain that the remote do not have a backlight . it do not sound that bad when I read one reviewer say that , but in reality , it be a total pain . I hope Epson update that some how and make it available for purchase . a remote mean to be use in the dark with no backlight make no sense at all . overall , we love it ! I be sick because the price be $ 499 when I first see it and the next day it have jump to $ 592 . have not go back down since . ca not wait to use it outside .
