I love these things. They are a great buy for the price. My mom had gotten 3 from a membership store and put them up in my house. When I moved home I was soooo glad to find them online and ordered 2 more for the livingroom. The price is great, Amazon ships QUICK, and they work great!!! My master bed is on the side of the house where the sun rises and the furthest room from the A/C so it gets HOT! I put two of these in my bedroom and one in the master bath and it cooled the rooms down tremendously!
The only negatives that I have are that they are a bit hard to cut, I actually broke one of the knives that come with them in half, so was glad I had ordered two shade at the same time. Also I have one that the material came lose from the top so I have to superglue it back. And lastly make sure you measure accurately or you will still have some sun that comes through on the sides, other wise they work great.
Overall I am VERY happy with my purchase and will be putting these in the rest of my rooms. I only wish they came in more colors and sizes.
Work great!!!!
