just like another person say , this product be garbage . I buy the 120 ft screen . I install it -lrb- pay someone to do this -rrb- and roll it down to start view a picture on it . the screen look great and I be happy until it be time to roll it back up . the retract mechanism do not work and my screen wont roll up no matter what I try . now Amazon want I to pay to ship this back and its look like it will cost a fortune due to its size . such a headache !!!!!!!!
