I received this on 11/29/18.  The box was damaged and had been taped over where the opening was.  Not certain if it had been opened before.  It had no instructions inside, but it doesn't clearly say anywhere that there should have been, and I'm guessing the manufacturer thinks it's easy enough to figure out. The "material" that is supposed to be the "shelf" feels like paper thin plastic, and the very first one I attempted to put on one of the poles, ripped very easily.  Cheap, cheap, cheap.  Don't waste your money.  I am very disappointed.
