Bests & Worsts Reviews from Amazon

There is no way this can be an energy efficient room darkening panel. I bought one just to try it out and this is pathetic. Like one of the reviews said, it's a step up from a curtain sheer. I will add a picture so you can see the morning light coming though. This is not even direct sun light. It's a pretty curtain, but most certainly is for decorative or regular curtain jobs. It's not see through so it has that going for it. But it's not room darkening or energy efficient that's for sure. I guess you get what you pay for.
