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.

Clean Look, Sturdy — can’t ask for more!
Size: 6 Panel-119"W, Color: Grey, Size: 6 Panel-119"W, Color: Grey
Really like how it folds so I can create kind of a doorway with two of these. Pretty easy to assemble and has an uncluttered clean look due to the smooth fabric and nice color. Oh and it’s sturdy enough for pets.

Lovely, but lightweight

Attractive and does what I needed, but is very lightweight, so must be secured.
