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.

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.

The curtain is not effective The curtain does not performed as advertised. The noise reduction effect is minimum. Customer service did not follow up my questions until I emailed them the second time. Even then not all my concerns were addressed. The curtain can be functional as a blackout or thermal curtain, but not so much as an acoustic curtain.

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 Maybe I got outdated instructions.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.

The instructions were missing a few… The instructions were missing a few details like rotating the piece that holds the bar in place. The curtain makes absolutely zero difference in noise level. The magnetic strip is pulled off the wall by the weight of the curtain.
