Cheap, screw holes don't line up, screen is to short, and bars take WD-40 and a mallet
This has been my worst purchase on Amazon ever. DO NOT BUY. My first issue was that bars #4 and #5 would not go together, I ended up buying WD-40 and a mallet and that kind of got them together. Now I went to but the screen on (which is almost see thought) and the screen is to short. I can't attached the bottom bar to the tall bar. The screw hole is in the wrong spot, so the screen is not secure. No amount of pulling on the screen will make it grown .25" longer. Since I can't get the bars secure the walls are not steady and fall over easily. The feet did go together very nice. I can't return them according to Amazons policy. I bought 2 sets. I'm not going to try to build the other set I have. And I can't take apart the first set, since the bars are so tightly together. Also the polls have rust on them.

Very Poor Built Quality
Color: Black, Size: 3-Panel
They use cheap tarp like cloth that you might find on a tent, so it is not suitable as a teleconferencing background without blur applied. The legs are flimsy and lack rubber feet, so it will scratch floors. The tubing is flimsy and very hard to move and adjust. This is only good if you are setting it up somewhere like a gym or a garage.

Eye pleasing shelves with the ability to hold weight
Color: Light Brown, Size: 4
Great set of 4 wood floating shelves. I used these to hold precon decks and other commander decks for magic the gathering cards. Though they are on the smaller size, they still fit up to 4 commander boxes side by side and and withhold double that if I stack the boxes. I am very impressed by the quality and how much weight each shelf can hold. The brackets to hang them make the shelves even more sturdy. The shelves are very pleasing on the eyes and the wood color is very natural. The shelves were simple to hang by one person. They look very stunning and of great value. They hold all kinds of items and function perfect as a shelf and look wonderful as a form/type of wall decoration even without items on the shelves. Overall I’m very happy with this purchase and I will be buying more of these shelves soon.
