Good Room Divider
Size: 4 Panel, Color: White
This room divider worked great to mask my "utility area" in my living room because I'm low on storage space. It's functional and pleasing to the eye, but the quality could be better as there were pieces of debris on the unit and fraying strings. It also can tip over if not positioned just right. I do like the versatility of it though because even though it's a four panel I can fold in one of the panels and use the other three. Overall I like it, the price could be lower based on the quality but its good.

Lightweight and easy to move.
Size: 3 Panel, Color: Dark Gray
Very lightweight, easy to move. Looks nice in my room. I bought this to direct the flow of window unit air conditioner. Because of how we need to arrange the furniture, the a/c blew directly on us, making it uncomfortable. With this in front fifth a/c, I can arrange the panels to direct the flow out into the room instead of on us.

Cheap
Size: 4 Panel, Color: Brown
Looks ok. However, it is flimsy and peels. Not worth the cost.
