I buy this screen to host a Super Bowl party because it will be project in the living room with plenty of ambient light . watch sport and movie on my exist taupe color wall be fine at night but wash out in the day . I get this screen because of the 1.3 gain rating . after some research , I discount the smell comment -lrb- only 1 -rrb- , discount the poor delivery rating -lrb- again only 1 -rrb- , discount the edge problem -lrb- minor and unavoidable for size of rollable screen -rrb- and pull the trigger . the screen be deliver with a `` silver '' service from the seller , nice touch . they bring it into the house and offer to unwrap it but after inspect that the packaging be undamaged , I elect to unwrap it myself . the screen be well insulate with 2 layer of foam and the box edge be reinforce . mount the screen be a challenge by it be sheer size , 12 foot wide and the precision require to get the screw into the exact location but that be not a design problem . it be not any different from mount blind or window covering , really . Performance wise , I be completely satisfy . one corner have the slightest tension deformity that I expect to lessen with time as I leave the screen suspend for a period of time . the curl edge be present on both side but marginally so and really only be on the black border part and not on the white viewable surface . the motor be really quiet and it take less than a minute to deploy the screen 79 inch . nighttime viewing be fine , the 1.3 gain be not as good as the 1.6 gain I have on a previous screen but will definitely allow I to have a great Super Bowl party . there be a slight chemical \/ paint odor if you stand within 4 inch of the screen and purposefully sniff it , but it really be a non issue unless you be extremely sensitive and have poor ventilation .
