I read the reviews and took a chance on this anyway. There was some slight sagging on the roof tent, from inside the room...but after using two telescoping tent poles with guy lines to hold up the biggest, one piece, wall flap..the sagging went away. I'm debating on installing a piece of industrial strenth velcro to the center, between the awning and the tent for added support when the flap is closed up. Other than that, I have no other concerns or issues with my tent room.
