Excellent Customer Service
Color: 3 Panels Natural, Size: 3 Panels
It is a nice looking screen but when I opened the box, it had been damaged in shipping. I am giving a 5 star review because of the customer service I received. They were more than accommodating (so important when dealing with a large item such as this).

Looks great but not that sturdy
Color: 6 Panels Black, Size: 6 Panels
These are very nice they look really pretty. The only thing is they seem a bit flounder than they look online. I definitely feel like you have to be careful with somebody they don’t break.
