Good product, poor directions.
Color: Black, Size: B-88''W-4 Panel
The quality of the product was better than most at this price. The directions could have been much better even though I have an engineering background.

Nice partition for my basement
Color: Beige, Size: B-102''-3 Panel
This 3-panel room divider showed up well-packaged with all the parts and even a little tool for putting it together. The instructions were easy to follow, and while one person can definitely assemble it, having two makes it quicker and less frustrating. It does exactly what I needed—gives quick, easy coverage in an open area. I'm using it in my basement to hide the furnace and water heater, and it works great for that. It looks nice overall, but I picked the beige fabric (which is really more of a tan), and the black frame makes it stand out more than I’d like. A white or lighter frame would’ve blended better. Not sure that I would use it anywhere besides the basement It’s lightweight and pretty sturdy. The wheels make it easy to move, but it does get a bit wobbly, and the panel clips need to be readjusted every time you roll it somewhere new. Still, for the price, it’s a solid buy. I’m happy with it and planning to order another one.

Fantastic
Color: Beige, Size: A-132''W-6 Panel
I am perennially in the process of rearranging, reorganizing, getting ready for yard sales, changing the functions of various rooms, moving everything out of a room to do a deep clean, etc, which means that there is always SOME part of my house, if not the entire thing, that is a disaster zone. Having someone knock on my door triggers a "duck and cover" reflex because it's so embarrassing for anyone to see that I live like this. (I *feel* like I don't, really, because I know that all the various stages are all temporary, but when there's always something temporary going on, it might as well be permanent, you know?) So THANK HEAVENS for a room divider that is not only large enough to divide my uncomfortably long den in half the long way so I can shove all the messy parts up against the back wall -- that is not only simple and attractive and neutral and (this is important) NOT BLACK because I have multiple pets and anything black in this house will be pet-hair-colored within 20 seconds -- that not only has **SIX** panels for lots of options of how I want to divide the space/s -- but is also on WHEELS. Someone out there really does love me, it's true! The panels are stable *enough* - I'm not going to lie and say that nothing is going to knock them over, because I have some balance issues, and I also have cats, and both of those circumstances has resulted in a mess on at least one occasion. But in the cats' defense, they've never dealt with a room partition that didn't hang from the ceiling before; and in my defense, I just grabbed the first thing I could reach on the way down. Not the product's fault in either case. Assembly was a little dicey as I am currently in **bilateral** (oh yes, that's fun) wrist braces, so I had to give up until I had help. But I think if you're able-bodied, you shouldn't have any difficulty. The only down side is, now that I've hidden away all the mess so I can break out the holiday decorations, you know what happens next, right?? That's right... the PERMA-MESS ZONE. Oh no. Oh well.

Difficult assembly, doesn’t fold well, looks good fully open
Color: Grey, Size: B-88''W-4 Panel
The instructions for this divider are very inadequate. After having to redo parts of the assembly, I have finally assembled it. The divider itself seems very nice when it is fully open, however it is not possible to fold it well as all the bars with the wheels go in various directions making it impossible to fold it neatly. And it has a large footprint. It is possible that I did not assemble it fully well because of the lack of adequate instructions. I am not even sure if I will keep it because I need to fold out of the way when nothing in use.

Slightly challenging build
Color: Beige, Size: A-88''W-4 Panel
This was my second screen set I've purchased, first of this style. Not the easiest to assemble. Lots of pulling and tugging; not a highlight in my day.
