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.

These are PERFECT for my Art Show coming up!

This is going to be PERFECT for my Art Show display. And also....EASY to put up and take down as well as store. I'm so grateful to have found them! They are super light weight. And sturdy for my application. And elegant and have clean lines for my display. I have ivy draped and also fairy lights which make it look classy yet simple! Love them!

Great for using behind me on Zoom calls

Color: Black, Size: 1 Large Panel

This works great as a place to put tapestries behind me when I'm on Zoom calls... much nicer than blurring out the background. Easy to put together, large, works great.
