Worked amazing during christmas
Color: Black, Size: 6 Panel
We had a ton of people over for Christmas so I had to make an extra place for someone to sleep so I used these and surrounded an air mattress and made a small shelter basically. The dividers are light but sturdy , not heavy duty of course but not expected for this price. They do an excellent job of blocking out light and are not see thru and worked very well. Assembly was straight forward and even comes with an included wrench but I used my own to speed the process. 100% satisfied

Satisfactory
Color: Black, Size: 6 Panel
Everything was advertised. But the box it was shipped in was torn up pretty bad and taped up to compensate. Nevertheless, the product itself was not damaged.

Easy to use.
Color: Grey, Size: 6 Panel
These are easy to put together and to use. We have used them with all the panels. We have also used them broke down into 2 and 3 panels. They work well for blocking views. They don't block noise or help quiet the room being used, however. Only bad thing about them. We use them for our Auxiliary meetings.

Easy to assemble. Still used for over a year 🙌🏾
Color: White, Size: 6 Panel
Everything is perfect! I would buy again in other colors and heights if I need additional separation in the basement.

Cheap Garbage
Color: Black, Size: 4 Panel
This item is just cheap crap. Shoddily put together, shoddy materials, and looks cheap. If you’re just putting it in a space that you don’t really care that it’s cheap, then it might be fine for what you need. But don’t expect much.
