Had trouble retracting it at first because the dowel that rewinds the screen fell out of its socket on one side. Easy fix with a screwdriver. However, 2 of 3 screws don’t tighten; they act more like pins to keep the end cap from popping off.
After realigning the dowel, I picked up the screen to mount on the tripod and the dowel fell out of its socket AGAIN. I put some masking tape on one end and wrote “this side up” so it wouldn’t pop out again due to gravity and naïveté. Would’ve been a five-star product, otherwise.
