I was very sceptical about the claims associated with these curtains,if not shocked when they actually did hide the brightening of the sun;kept the summer heat out(even when the air conditioner was given a break). What really surprised me was the beauty of these curtains and the potential I've never found in any other curtains or shades that cost me hundreds of dollars,yet allowed the brightness of the sun's rays to peek through. Dust was never noticed by me when it came time to wash;which was very easy to do without damaging the features within.I'm so glad to have been chosen by Bazaar Voice for this testing campaign because it made a believer out of me.
