Amazing that they could have made this work much better if they made the corners aluminum or steel, but they are plastic and cause much lose fitting the aluminum rail form. Fabric is good, white on the other side is fine. I will find it useful but if I could cast steel corner fittings it would be much better. It would be another $50 with those parts at least anyway, but it is a convenient way to put a display backing up without a large trailer to hold single panels.
