JUNK!
Color: Grey
This is the worst product in every way. I ordered a similar one previously and thought I was getting the same product which was great, no this is a piece of junk. I would have gladly sent it back but I needed it. I feel sorry for anyone who tries to put this together without any mechanical ability. I have plenty and it was still a nightmare. We will surely not be purchasing anything from this company in the future. The previous one I bought was a (Kecreque Room Divider). Is is a quality product!

Nice looking and lightweight
I bought this to put in front of my basement doorway where I am missing a door. I don't like my cats in the basement and this works very well. However, because of the panels being up on 2 inch or so tiny stilts, my cats can still get through. So I have it upside down and will be putting gliders on the "bottom" of each panel. Note that it did come with gliders on the little stilts.

Know what you're doing before you order
Color: Grey
There's a very high quality item easy to assemble last a long time it was pretty nice. For the first one. My roommate talked me into buying the second one and then he backed out of the deal he didn't have the money. So I returned it at the Amazon store and like a boomerang it came back. I end up having to buy it anyway you're still sitting in the box
