Functional divider for windows privacy
Size: 8 Panel, Color: White, Size: 8 Panel, Color: White
I ordered both a six and eight panel version of the white divider. There was some confusion on the FedEx deliveries. The eight panel divider arrived at first, but Amazon showed both as delivered. I had to contact both the seller and Amazon to learn that the six panel divider was to arrive the following day by FedEx, which did occur. Both the boxes were a bit dirty and had some small punctures. This divider had a top area and bottom area set of plastic wrap tapes, both of which were loose or undone. (The eight panel divider was not so, and properly wrapped.) The top of thid divider looked a little dirty, but passable/cleanable. The seller should consider wrapping the entire product with bubble wrap to protect against potential delivery/shipping physical and water damage. (FedEx left the box by my outside door, which could have gotten potentially soaked in rain. One better be home to take delivery if the weather is bad.) This said, the divider was easy to set up, with all the metal hinges working. No assembly was required, just unboxing and standing up. The left side was a little uneven on the bottom with the first panel, but ok. In combination with my mini-blinds, it provides the additional layer of privacy I desired. I even don't notice outside headlights and tailights through the windows with my room lights on. Additionally, the divider is easy to adjust to allow access to my windows for opening and closing. So, no need for me to hang curtains and damage my drywall. Overall I give the product a C grade because of the lack of protection for the FedEx shipping. (As a former University told me years ago, "The A has been cheapened. In this class you will work for an A." And, I got a B. So, I am a bit jaded. :-)) Lastly, if one had cats and dogs, or even small children, the divider could be easy for them to topple over. I would not consider these dividerd in that case. My motto is, "Safety first."
