Easy to use in the right temperature.
Good product but messy, expensive, and in my case time consuming.

Product is as it said it would be. I read reviews and watched YouTube videos prior to purchasing. I knew it was going to be messy. I did a lot of prep prior to the application to an a small attic space. I basically made a plastic room in the space directly below and sealed it with tape. The nozzles will clog if you don't remove the accumulating foam that forms at its tip and if you let it get too big it will cause the spray pattern to go haywire. Although I'm sure the product is more than adequate in terms of my needs I still found it to be a bit too expensive but it definitely got the job done. In my application I needed to layer several times so that the cold would stay out. My issue in the attic space is that ice would form and subsequently cause water damage. I had proper vapor barrier and the attic was vented. Didn't matter. The space is probably 3 cubic yards and it filled it up about 3/4s.
Some thing is actually reading the instructions. There have been complaints about the Volume or yield that people are getting from the tanks. Clearly states that things have to be 75° or warmer for 24 hours in order for you to get a full yield of the product. My house was set at 70° and the outside temperature was 64°. I used heating pads and taped them to the sides of the tanks. The tanks raised to a temperature of approximately 78° and was perfect for use. Without using that method I would not be able to get the things over 70°.

Will also work to spray inside walls, but extra straws needed

Very messy, but gets the job done. Insulation worked for my old house without insulated walls. I'm going to do my garage next!
