Does the job, but assembling by yourself is a nightmare
Size: 4 Panel-88'', Color: Black
Does it do the job? Yes, although as others said there are small gaps but it's not a huge deal. The price is also good. But the reason I'm giving it a 3/5 is simply because the assembly for this was a complete nightmare. I honestly don't think I would recommend this to anyone unless they have another person to help them assemble it, because doing it by myself was terrible. I don't think I'd buy this again, I think I'd opt to just spend a bit more money and save myself the trouble personally.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it. Couple things: 1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky. One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection. Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it. 2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless. 3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together. 4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place. 5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options. NOW on to the utility itself. 1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great! 2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world. 3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it. All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.

Great for using behind me on Zoom calls
Color: Black, Size: 1 Large Panel
This works great as a place to put tapestries behind me when I'm on Zoom calls... much nicer than blurring out the background. Easy to put together, large, works great.

Good quality, very adorable solution.
Color: Black, Size: 1 Large Panel
Easy to put together and take apart. Wish it had a storage bag of some sort—that would be very helpful. Used it for our mom while she was on hospice at home. The wheels made it very easy to move around as necessary. Nice and tall and wide for privacy. Highly recommend.

Nice, large room divider for privacy
Color: Black, Size: 1 Large Panel
Easy to assemble. Fabric screen covers the large frame very well and provides privacy by separating spaces. I would not exactly call it sturdy, but it does the job and stands freely with no problem. It’s lightweight and portable if you need to move it. Came with a screwdriver and wrench tool for assembly.
