Item is high-quality, works as advertised Item is high-quality, works as advertised. I really like my Acoustidoor! I haven't had as much time to use it as I would like, but I've done some testing and it definitely reduces noise and sound bleed at the threshold where I installed it. Be sure to measure carefully: my item was delivered with precisely the measurements that I selected.

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.

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 Maybe I got outdated instructions.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.

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.

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.
