Great privacy screen
Size: 6 Panel-119"W, Color: Beige
I have a studio apartment and the bathroom is in my bedroom. I bought this to section the area off so guests can use my bathroom without seeing my entire bedroom. This is perfect for that! It looks very nice and offers alot of privacy. The screen is fabric and good quality! I’m a middle aged woman and put it together myself in about 2 hours. Love this!!!

Nice divider 6 panel with wheels.
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
The wall works great , and I put it together by myself. I only gave it what I did because I have to move one or two of the panels on one end around a bit daily to make an opening to pass through. I find I have to check the screws that hold those legs/feet on frequently and retighten them. Beyond that everything was pretty good quality. (I ended up magnetizing an Allen wrench to one of the feet.) I also put on motion lights to the rollers so you’ll see them and don’t trip.

Room divider
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
I was looking for something to separate my two boys and give them both their own space. So far this room divider has worked well. It’s 6 feet tall and the fabric is dark and thick. You won’t see anything on the other side. Good quality and easy to assemble ✅

Too Cumbersome
Size: 6 Panel-119"W, Color: Black
Didn’t realize there were over 100 pieces to put this thing together. Had I been advised of that I would not have ordered this thing. Wayyyyy too much of a production to put it together. Nope. Returned.

Great Product, But Non-Existent Seller Support
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
The Good:
Well Designed: Sturdy and aesthetically pleasing.
Effective: Perfectly obstructs the afternoon sun glare from my monitor screens.
Moderate Assembly: Straightforward and easy for the most part.
The Bad:
Defective Part: One crossbar end was missing threads, preventing the assembly of the sixth panel.
Zero Communication: I emailed the seller as instructed and waited 8 days with no acknowledgment.
Return Logistics: Amazon offered a return, but the box is heavy, and disassembly/repackaging would be a major task.
Final Verdict
I really like this product, but I’m deducting two stars for a total lack of customer service. I’ve decided to buy tools and fix it myself rather than deal with a heavy return. I hope the seller sees this and reaches out. The lesson learned is to check every part of a product before assembly.
