I have no negatives about these blinds. The measuring instructions were clear and the blinds fit perfectly. They were super easy to install and do a good job of keeping the cold air out.
Love my new blinds. I wanted a new look for my master bedroom, but since I have a patio door and a tall window, I have trouble finding anything that fits both. Your measuring instructions worked great and they are a perfect fit. I'm 65 years old and had no problem hanging the window blinds by myself.
Use product to reduce harsh glare of bright afternoon sun and to reduce temperature. The shades do a great job! And while they do a good job at all of the things mentions they sill allow you to see outline of trees and the outside.
