Don’t waste your money. Not effective. I bought acoustic grade inserts and actually went with the self install kit which btw they say outperforms their actual insert….it hasn’t helped. Same issue and now just out hard earned money.

I have a lot of complaints about this…
I have a lot of complaints about this experience. First, I was not aware that I'd have to install brackets in my window casing. That's a no go. Second, the cream-color silicone was dirty. I had to put a lot of elbow grease into cleaning it, and it's still discolored in one spot. Third, sound in the room is now driving me crazy. The company does say the Indow isn't effective with low frequency sound, but this seems to have also done something with sound that my ear and brain detects and abhors. It's a pulsing, barely audible bass, an infrasound. Fourth, the communication was great, except for two things: I was told to hold onto my laser until they told me to send it back. Then the communication about sending the laser back was buried in a longer automated note, and I got sick of receiving those, so I missed it. But even after I sent it back, I kept receiving messages about it—it was stuck somewhere, but it's just the persistence that I dislike. They were very nice about stopping them and very responsive. I give two stars for that. I definitely regret my purchase and will now have to spend additional money, at least as much as I did on Indow, to replace the Indow with a more permanent glass solution to stop this sound.

Fantastic!
From the initial contact we have had a great experience. The measuring kit was easy and kind of fun to do. Directions were easy, even for someone who usually has to measure everything multiple times. They were so patient when we had to delay our order, kept our info and never pressured. Everything came clearly labeled and fit correctly. And the results!!! We live on a really busy road and they cut out so much noise. They literally have saved our sanity! Love.

Absolute scam of a company
Absolute scam of a company. I paid a large premium for the "accoustic" grade windows which the companies website says is 1/4 inch thick. When they arrived, I knew right away it was wrong, it was not even half of the thickness promised. I have just never been taken advantage of like that in my life by a company. Upsetting, so beware

Zero noise reduction!
I purchased inserts for my bedroom to help reduce road noise. I'm utterly disappointed as I ordered the acoustic grade and there is ZERO reduction in noise. These inserts are about as useless as a piece of plastic wrap on my windows! I have read numerous other reviews that had the exact same issue and their solution was always to adjust the fit. Well...they are fit as snug as possible and I have had other people look at the windows to ensure this and there are no gaps and the seal is secure. These inserts that I waited months for are totally useless and they are 100% fit as snugly as possible. Moreover, I was told by my sales representative that they were easy to take in and out and that some clients do so everyday to open their windows. This was a huge selling point for me. But, what was not disclosed is that these windows are heavy and given how much I need to manipulate the sealing to ensure a tight fit, I can't imagine ever taking the inserts out to open these windows on a regular basis. I feel like this was also falsely represented or I never would have purchased them. Incredibly disappointed. Save your money!

First of all…thanks Indow!!!
First of all, I am an architect and I needed Indow inserts for 3 old casement windows which had warped and are now stewed closed on an enclosed mahogany framed porch. Working with Indow was very organized and really quite straightforward. Pricing was reasonable and their checking and confirming my measurements was extremely helpful!!! Indow inserts arrived on a timely schedule, beautifully packaged, and safely delivered. The inserts fit perfectly and have markedly reduced the incoming sounds (from the above ground Subway)!!! All good!!! Hope to do additional fixed windows on this enclosed porch in the future!!! Thanks Indow!!!

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. (Especially THREE YEARS later)

Great inserts, but lots of labor
Pros: The product itself is great and I'm stoked to have them done. They honestly look fantastic- like the windows look better and more buttoned up with the inserts. The service was also stellar.
Cons: every step of the process from measuring to installation is way more difficult and time consuming than expected. Measuring 10 windows took 4 hours for two people. Unboxing/installation/cleanup took one person 5 hours. That's unskilled hours, but at $400 each plus labor you start to wonder about relacement costs.
The videos make it look like you can easily pop them in and out any time, but that would be a lot of trouble and risk damage. I got this for renters and would not trust them to handle them, so I must store them for summer or have windows that don't open.
Finally, some elements felt "snuck in." E.g. laser measuring sounds very automated until you learn that checking bows requires a string, a ruler, and 4 hands, plus a separate tool for diagonal measuring. Similarly, I thought I'd pop in the inserts like the video, only to find that they all required additional hardware installated on the frames for the previously undisclosed safety chains. Great! more measuring, drilling, adjusting, readjusting, cleaning, micro adjusting, recleaning, etc
Summary: I recommend this product if you know what you are getting into. If you only need a couple of windows, go for it. If you have 10 historic double hung windows, be ready to bust your butt and hire a helper.
