Absolutely outstanding customer service. They have been very responsive and, without charge, they replaced a few minor parts I had lost which was entirely my fault.

The app works very well for scanning my purchase receipts. I like that even the free option allows me to download reports and images of all receipts as PDF or .XLS, as being able to store this important tax information locally gives me a sense of security. The free options are very generous and I am about to switch to the paid option for my more intensive usage, but the free version was still very useful while I was trying it. The free version could still do everything I need but with slightly less convenience.

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.
