Know what you're doing before you order

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

Must have for at home workers!
I bought this divider because I work from home and wanted to have a professional and neutral background for video conferencing. There were other dividers that I contemplated purchasing because of the variety of colors but ultimately decided to go with this divider because of prime shipping. I noticed in the reviews of other dividers on Amazon a lot of people talked about cracks. I noticed a few cracks on mine but they are small and minimal in appearance so it does not bother me (see pictures). Overall, it came in great shape. I love the color of the divider. I was concerned it would come solid brown based on the pictures but it is more rustic, which I love. The dividers are tall and long so it covers a great amount of space. The hinges go either way which is also a plus. I will say it seems slightly unstable on carpet but it would only move if bumped into so that is not much of a concern. Most likely would be more sturdy on solid/ hardwood floors. Overall, I am super happy with my purchase. Definitely worth the price with fast 2 day prime shipping and no assembly needed.

JAXPETY Room Divider Panel 6Ft Privacy Screen Wall Divider 88" W x 73" H - 3 Panel Black
Color: Black, Size: 3-Panel, Color: Black, Size: 3-Panel
I was looking for a screen to use while making video calls. I am on a budget, wanted something easy to put together, and would hide my apt in the background. Being on a budget, I thought my purchase qualified for the coupon. I was mistaken but contacted the seller. I received a quick response explaining how the coupon was applied. I was happy with the quick response and explanation which I verified when I went back to the page.
The once all put together the screens are light weight and fairly easy to move. they do not seem to be made for easy daily breakdown. However, if you should need to take them apart to move or something, easy to break down. Depending on lighting will depend on if you find them transparent. I don't mind possible vague outlines; I was looking so no real details of my belongings in the background could be seen (shelves; figurines; etc.) My apt living room has no overhead light source, so floor lamps give light. In the 3 photos of 2 of the screens put together; the first is with a lamp in front and back of the screen as well as a tv on. The next has the tv off lamps still on and the screen reflecting the pc monitors. The third is with both lamps and the tv off, monitors on but not as reflective.
In the box, you have all the parts you need as well as a small tool and an instruction manual. Item 'bags' are number [though they may come off in the box] to assist with assembly. Now assembly can be easy or hard depending on your abilities and the area you are working in. I have bad knees, so kneeling was not an option for me. My first attempt to put this together, I put the 'feet bases' on while still connecting the top bar. It made it twice as hard, and I stretched the fabric more than was necessary causing wholes around some of the stitching and stretching them a little. As well as causing some stitching to come undone on one of the pictured areas. Once I took off the 'feet bases', I had an easier time to screwing in the top bars. You will still need some hand strength, which I don't have much of, but it is possible. I use the grip things to open pickles jars.
Once the screens were assembled, I followed the instructions of tying an outer screen to the inner screen and using the Velcro 'privacy flaps' to complete the connection. I have what I think is low shag carpeting which they were able to stand stably on once I wiggled them into standing straight up and in place.
Given these post pandemic times, I am overall happy with both the divider and the price. The 2 things I do not like about the divider is the difficulty putting in the top bar [after connecting the top and sides] and storability when not in use issue I am having. Others with larger space will likely not have the last issue.
