Works as advertised! I live in downtown LA and also have an east facing apartment. the traffic noise can get kind of loud and at night can be disruptive. I found Residential Acoustics online searching for solutions and I took a chance on them. Not only is any sound at all barely even noticeable, the curtains also completely block out all the sunlight that used to pour into the bedroom, making it much easier to stay asleep until its actually time to wake up.

RIP OFF!!! DO NOT WASTE YOUR MONEY!!! This product is complete trash. Using a professional decibel meter while the curtains are up it 100% does not block out any sound or made a difference. Then they tell you there are no refunds which is complete bull and should be displayed on the ordering page. I've had to get my bank involved to get back $800, because I bought these overpriced curtains that do nothing but block out light. Save yourself the headache and stay far away from this scam of a company... Im prety sure they fake all their website reviews as well.

Poor Customer Service Do not buy this product. After following the measuring guide as well as contacting the company before purchasing, the product I received did not fit our windows. The perimeter seal is attached very sloppily and is not square on the curtain so it does not line up with our window sill. After talking with customer service, the only option available to me was to pay $150 to have them redo it. That being said, I also think the product looks worse than it does in the photos on their website. Avoid this overpriced poor product.

Okay While they do dampen some noise, they're not effective at blocking out low frequency noises. The website notes that this, but I thought I'd give it a try. Blue color is attractive and they look good. Installation a bit confusing because the velcro is inset from the edges. Took longer than expected to receive the blinds. Overall, they're okay, just not very effective at fixing my particular issue.

Good looking, smooth installation, no perceivable difference in noise level I was excited for this product. Buy it if the only thing you care about is blocking light. If there is any difference in how they block street noise is not significant enough to improve your sleep quality. I'm still waking up at 5:30AM together with the traffic. At least they look nice :) I'd hate taking them off after making all those holes in my window frame. My experience makes me question the origin of the reviews on this site, but oh well.
