Worked well to separate space!
Size: 132‘’Wide-6 Panel, Color: Grey
Did the job I needed. I created a hang out area in part of the basement for my pre-teen and wanted a little privacy/separation for the area. Not hard to put together and was to move around. I do wish the legs Ira on with the rollers didn’t jet out so far.. is quite a tripping hazard..

Perfect!
Size: 88‘’Wide-4 Panel, Color: Grey, Size: 88‘’Wide-4 Panel, Color: Grey
This is exactly what I was looking for. I created essentially a doorway into the pantry area I have in my basement. I had the bought a screen years ago that hid most of it but this completed it. I ordered the 4 panels, for the size, and created a "door" of out the two.

**Product Review: Disappointing Experience with Misaligned Pieces**
Size: 88‘’Wide-4 Panel, Color: Grey
I purchased this product with high expectations, but unfortunately, it turned out to be a major disappointment. The biggest issue? The pieces are terribly misaligned. Assembling it was a nightmare, as nothing fit together properly. The holes didn’t line up, the joints were uneven, and I had to force parts into place, which only made the situation worse. Something that should have taken 15 minutes took hours trying to screw the poles together.
This product clearly lacks quality control. For the price I paid, I expected much better craftsmanship. It's incredibly frustrating to spend time and money on something that is so poorly made. I would not recommend this to anyone unless they want to waste their time and end up with a subpar product.
Avoid this at all costs!
