Screws dont fit
Color: Beige
Got the frame set up no problem. Tried to get the legs secured, and the screws dont fit through the leg hole. Without the legs being secure, the divider will not stand up on its own. Total waste of time and money.

Window blocker
Color: Black
This is a nice blocking items, or to block windows. The worst part is putting it together, not an easy task. Nothing is labeled, it’s like a guessing game, it is still loose and crooked.

Don’t waste your money please
Color: Black, Color: Black
This was the absolute worst. Trying to assemble this was a total headache. None of the pieces seem to match and the end result was just horrible.
