I have often bought curtains from online market places, including several times from Amazon.
This curtain is the worst of all purchases.
The fabric quality is poor & is poly mixed with some other fibres.
It has very poor drape.
It is not even darkening by any stretch of imagination, nor there is any triple layering as claimed.
I had to additionally put the polyester lining to bring down the sun's intensity. I have decided to discard the curtain and can sustain the overall loss.
I would advise buyers to use their discretion before buying this curtain brand and not the stated claims, which is all hot air, tall and bogus.
