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.

Pretty good, especially for this price point.

Color: Beige, Size: 21.5"- 1 Panel

This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.

Easy to manage

Sturdy, easy to manage and roll around. The material for the walls is of a decent ply as well
