Packaging contents
Color: Grey, Size: 34"- 3 Panel
Item is as described however this one appeared to be open and some parts possibly used. Example pole packaging mislabeled one had the letter K as a part there is no letter K item in the instructions. Another pole part had a taped on letter A which is completely different from the others thus indicating that it was opened or substituted. Finally after the partition was completely put together one of the bottom screw connection anchors came out making the partition unable to stand. I'm going to have to rig something up in order to get the anchor connected to the bottom panel. In closure the partion could be very acceptable and do the job if it was new and parts labeled correctly. I have pictures of all parts and packaging errors. Would buy again if new. I'm going to pursue some kind of compensation.

Great product
Color: Grey, Size: 34"- 6 Panel
This room divider is great. It was easy to put together. I was worried about it standing up right and not falling over. It stays up perfectly and is very easy to move and adjust to the shape I want it. Also, from one of the videos I watched it looked like the fabric was puckered in the panels. That is not the case at all. The fabric fits tightly in each panel for a nice smooth look. I would definitely recommend this and would buy again if needed.

Awful.
Color: Black, Size: 22"- 4 Panel
Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

Excellent privacy shade.
Color: Coal Black
This delivered on exactly what it promises. So happy with the quality for the value. The shades are a fabric, nylon like, that are attached with a pocket on one end and velcro that adheres around the bar on the other. This was incredibly easy and straightforward to put together. Every piece was clearly labeled, coordinated with the instruction sheet, and fit perfectly. Honestly, I wasn’t planning to leave a review but I was so impressed by how clearly labeled and well explained the instructions were that I felt compelled to note it. Especially for anyone who doesn’t like putting things together, or is used to subpar instructions, this is leagues above the rest. It’s such a simple build anyway, but after buying so many things that barely fit as they should, this stands out. It is lightweight and easy to move. Offers privacy when opened, then can be folded out of the way. It looks exactly as pictured. No complaints, it’s a solid item and worth the price.

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough. It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!
