did not perform as expected. My Indow windows inserts did not perform as expected. The constant road noise from traffic is still annoying, and there is not a tight seal, I can see space between the wall and window insert corners, also there is a condensation build up on the bottom. The wait for the took for the insert arrive was about three months, but I did received periotic emails on the order status, and Mr. Reed gave great customer service.

They work! They actually do work surprisingly well! Don't expect 100% noise reduction, or you will be disappointed. But there has been a significant drop in the road noise in the rooms where I bought the windows, such that it does not bother me anymore and I tune it out. The installation and measuring process were a lot harder than advertised, recommend getting a handyman to help.

Costly But Effective Our Indows have significantly reduced the noise levels in our bedroom. At night, background noise is essentially zero despite living next to active train tracks. The process of measuring our windows was easy with the kit provided and installation was also very simple. The inserts did require us to remove our blinds and get window treatments which we had hoped to avoid. Also, they were pricey, but we got what we paid for and are happy with the improvement of our sleep.

Bad experience Bad experience. I bought this product expecting a noise reduction which did not happen whatsoever. The only response I got is that performance can not be guaranteed. It was so frustating because they dont give you money back either. $700 trough the drain.

Cut bedroom decibel level in HALF. Impressed. 5 stars for a great product. I live next to a busy highway and it's been incredibly disruptive to my sleep. Indow has cut the decibel level in my bedroom by HALF. Impressed. My only gripe: Shipping took about a month, and instead of just saying "shipping takes a month" (which I would have been completely fine with) the company auto-sends an email after purchase saying "We have worked hard to absorb the supply chain issues that have affected the entire world". This is unprofessional and annoying and as dated as listing your pager number on a business card or fax number on your website. Companies need to stop blaming acts of God for your poor customer service department or slow response/delivery times. Deal with things out of your control, and stop making excuses because of them.
