Very impressive!
Size: 6 Panel, Size: 6 Panel
I didn't think this screen could possibly be as good as some of the reviews seems to suggest but it had a good rating and seemed like it may be a good match for my needs, which were to create a backdrop for online meetings in my garage/home office. Wow am I surprised by the quality and functionality of this screen. 1) It is really maneuverable due to the two-way hinges. I felt like a kid with a new toy playing with all of the ways you can configure this screen. 2) It's very sturdy and yet light enough to move and store if needed. 3) No weird odors, has a light woody scent, barely noticeable. 4) Its a very high quality screen, beautifully built and very pretty. 5) Its dimensions are as described, a full six foot tall. I spent a lot of time shopping for a screen and am very happy that I chose this one.

Perfect experience ！！！
I love this divider. It is long enough and easy to move around. The 360° hinge can be adjusted to any angle I like. Perfectly hides the awkward corner so I can't see it all of the time. And the light color and pattern in the panels is beautiful. I will buy another one.

Works well
It's lightweight and the right height and width. It folds easily in either direction. It was challenging to put together, but with help from 2 friends, we did it. I'm hoping it will hold up during winter weather, outside on my deck, as a vanity shield when removing my swim gear.

Great purchase!
Size: 6 Panel
I absolutely love this thing. I've had it for over a year now, and its held up beautifully. I used it in my apartment as a divider between a very large living room, and its worked great. Sturdy, no issues.
