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 Maybe I got outdated instructions.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.

Helps enormously in NYC! The curtains really do help lessen the loud street noises in NYC. My only issue is that the hooks were not strong enough to hang the curtains--perhaps because my ceiling to floor length curtains were especially heavy. Fortunately, my handyman was able to reinforce the hooks with additional hardware, so my curtains are secure.

Item arrived defected, customer service only has ~10% response rate. Item arrived defected. Emailed customer service with no response for a week. Finally call answered and was asked to send back for warranty repair. Since then, no response to emails and phone calls for weeks. Ordered one month ago, still got nothing.

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.

Does nothing vs train horns Purchased after reading a review on their website saying it was effective vs train noise. There is a train track a half mile away that hoots in the middle of the night. The curtains do not dampen that noise at all. They mildly dampen other noises, but do not do anything towards the reason I purchased them. I should have done more research on reviews before committing $700. Frankly, I feel like I've been scammed.
