4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.
Size: 4 Panel-88'', Color: Black
Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.

Attractive
Size: 4 Panel-88'', Color: Grey
The assembled product is just as described. The screens look great! I am using them to hide the cluttered shelving in my garage. The area now looks quite neat Something I must say, though, is that the assembly was extremely difficult. I had to use a silicone spray and some pounding to get the A and B poles to fit together. Also, it required a great deal of strength to stretch and hold the fabric panels so that the bars inserted in each hem lines up with the screws inserted in A/B poles. I strongly recommend having a partner to help with the assembly.
while sc and screw into poles them once inserted intetchedtne end of each pole ( and B poles barely fit together. I used silicone spray on the end and then pounded them

Works

It’s beige and not white. Once install - hard to disinstall. Need a drill to put it together

Does the job, but assembling by yourself is a nightmare
Size: 4 Panel-88'', Color: Black
Does it do the job? Yes, although as others said there are small gaps but it's not a huge deal. The price is also good. But the reason I'm giving it a 3/5 is simply because the assembly for this was a complete nightmare. I honestly don't think I would recommend this to anyone unless they have another person to help them assemble it, because doing it by myself was terrible. I don't think I'd buy this again, I think I'd opt to just spend a bit more money and save myself the trouble personally.
