Works Well Works well. Turns the volume down on outside noises (except low frequencies). Loud sounds become moderate. Moderate sounds become barely-audible. Quiet sounds become inaudible. My only complaint is the instructions it came with were misleading on how to connect the brackets to the bar. Maybe I got outdated instructions. I suggest that the company advertise more clearly the fact that it's made of EPA rather than PVC MLV. Standard MLV is made of PVC, which offgasses toxic fumes indefinitely. EVA does not. This product has a smell for a couple weeks - but at least it's a harmless smell.

Completely blown away I was skeptical at first but boy, what a difference. I live in a 1920s house with older windows that let a lot of sound through. This curtain completely transformed my living room -- it's like being in a solitary bubble. A bonus that I didn't expect is that the curtain has thermal properties as well; it's helped to keep my room cooler in the Florida heat (not to mention blocking a lot of light!). It did take 2 weeks to receive my curtain, but it was totally worth it. The company was responsive to my emails too, which is nice.

Noticeable noise reduction The curtain is helpful in reducing outdoor noise as well as early morning light. It's heavy, but the hooks provided make mounting straightforward. Raising the curtain is more work than a conventional curtain, but the straps work well. I'm a satisfied customer.

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.

It just works...okay The ordering and delivery experience was excellent. As far as product functionality, I would not buy this curtain again. It is very cumbersome to roll up and down and already has started to curl at the bottom. It barely blocks low frequency noises at all (in fairness, this is explained, so I knew that ahead of time) but does provide a little bit of relief from other outside noises. If this product were $150 cheaper, I would say it's fine, but otherwise not worth the cost! It is excellent at blocking out sunlight though.
