Love the look of this after it’s put together. It’s pretty sturdy and the connecting clips allow you to shape it different if you need it to fit in a corner. We use this at work so it’s great for the space we use it in. A little hard to store because it doesn’t fold up nicely because of the feet on it but I’m happy with it overall.

Does its job

Color: Black, Size: 4 Panel-88''

For the price the quality is decent. The only thing I do not love is the panels are attached to each other with 3 plastic clips. Only 1 side of the panel is actually attached to wheels. The other side kind of sits on the bar and is held in place with those clips.
