Item is apparently very fragile. as soon as i opened it and tried to set it up, one of the metal side supports snapped. the instructions are so very unclear and not helpful, its a good thing ive set up hundreds for my job, otherwise i never would have been able to manage it. as im setting it up, another support on the opposite side snaps. so now 2 different support bars have snapped. very cheap and wish i didnt blow $163.
