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.

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.

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.

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 Maybe I got outdated instructions.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.

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.
