Busted spring on one side....
Color: Black, Size: 28-70"W x 48-120"H (Pack of 1), Color: Black, Size: 28-70"W x 48-120"H (Pack of 1)
I would have given it five stars except for the fact that 1) the instructions that come with it are miserable so you will definitely want to refer to the photos they have in the advertisement here, and 2) it appears that one of the vertical poles has a busted spring and I literally had to stuff some socks underneath it to make it hold. Definitely an eyesore, so I'm not thrilled about that. With that being said, I'm in an apartment and I don't want to drill in the walls to hang a curtain rod. My sliding glass doors have a track that I was able to get brackets that fit over the track to hold a pole, but I had one window that I could not do that with. I thought this would be an interesting way to hang curtains without doing damage. I considered those sticky tape curtain rod holders, but I was reading a lot of bad reviews about them not holding or them taking the paint off upon removal. I figured this was the better option and it gave the room some nice aesthetics because my furniture is farmhouse white wood with black iron accents, so this blended really well with the aesthetics of the room. I know that most people who did reviews used this product as its advertised to be a room divider for privacy... So I figured this is a nice way to review using this product in a different way. I just really can't stand window blinds, as they look so commercial and industrial to me... I needed a way to make the space seem more homey. While this is working fine for me, the reality is I have white lace curtains, which don't weigh much. I don't know that I could recommend this product, even though it says it can support a bit of weight, with curtains that are too heavy. Some of that, in part, is due to the fact that one of my springs is broken so it's not very stable as it is. However, even if I was not having the issue with the spring being busted on one side, I still don't think this would be good with heavy curtains (especially if you like opening your curtains frequently). It did come with curtain hooks if you have the kind of curtains that allow you to use hooks to hang them. I do not. My curtains just slide onto the pole. If they were the type that could be put up with hooks then opening and closing them would probably be easier and maybe not as big of a deal as it is for me with the type of curtains I have. I cannot comment on longevity as I just installed it today... If anything changes I will try to remember to come back and modify this review.

Easy peasy
Size: 1 Panel, Color: Black
Bought this single-panel room divider for my son so he has a little privacy when he has to keep his camera on for online classes. It’s lightweight, easy to set up, and does the job—he can focus without me photobombing in the background. He can feel like he has his own tiny corner office, even if it’s just the basement.

It serves it's purpose!!

Product really works well & serves it's purpose! Great height & width. It's flimsy, but it will stand still when put in place.

Zero stars
Size: 1 Panel, Color: Black
The bars are impossible to screw in all the way so it’s not sturdy at all, trash and waste of time
