Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

Pretty good, especially for this price point.

Color: Beige, Size: 21.5"- 1 Panel

This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.

Wonderful Room Partition !

Color: Black, Size: 88"- 4 Panel

This product is made very well, packaged, and assembled with no problems. All parts and tools are included (except a Phillips screwdriver.) I put this item all together by myself on a bed to make it easy and simple. I made sure that every screw head was attached where the recessed dimples are located on the vertical poles, just don't overtighten anything. Everything fits like a charm, good quality, looks great, perfect height, rolls with ease, proper privacy, really impressive ! I got the 4-panel in black color. I would certainly buy this item again ! Thank you !
