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.

Keeps areas separated
Color: Black, Size: 6 Panel
Item arrived quickly. I use this to keep my cats out of a part of the cellar. Works great. They've figured out how to slip through side. I made a panel that covers those spots. Still the best item to keep area separate.

Nice panels
Color: Black, Size: 6 Panel
Gives good coverage, nice dark panels. Easy to assemble, light product and sturdy. I will recommend this item! Completely covers the back shelves that are for employees only.
