Falls over
Size: 8-Panel
The legs are so short/small and not heavy it just keeps falling over and it shows a pic of water on it and making you believe it’s for outside. No way, it can’t stand any wind at all. Also the directions were not that easy for most.

Great quality, very versatile
Size: 6 Panel-132‘’Wide, Color: Beige, Size: 6 Panel-132‘’Wide, Color: Beige
I'm very pleased with this item. It was not complicated to assemble but some items required dexterity and strength. The fabric panels are nice and tight and that's partly why it's a little hard to get that final screw in. I'm very pleased with the legs and the wheels. The metal components are nicely finished and feel substantial and endurable. I can easily fold this so many different ways… I can minimize the number of panels that are seen if desired and it can be straight or accordion. It's very stable which was hugely important to me because I'm fostering many many cats. It's not cheap looking and the light color fabric allows enough light to pass through that it doesn't darken the room substantially. I think the price was very reasonable

Good purchase
Size: 4 Panel-88‘’Wide, Color: Black
Very easy to assemble. Good quality. The material is thick enough to block the light and gives much needed privacy.
