We had been using a roll screen in our living room for about 20 years, but it didn't block out light, and because the windows faced west, it was so hot in the summer that the air conditioning didn't work very well. Then I suddenly thought, “I'll buy a blackout screen!” and looked it up online and bought it. First of all, I was surprised at how cheap it was. The previous one was more than twice the price. Then I picked it up at the store and carried it for one station, and I was surprised again at how light it was. When I actually installed it, the difference from the old one was clear. I'm glad I changed it. If I had to pick one problem, it would be that it's too long. However, as long as you don't lower it that much, there are no problems at all, so I can recommend it. *The photo on the left is of this product, and the one on the right is of the old one.
