I have had good results with this product in the past however the last 2 batches and their replacement did not work as desired. Had a violent reaction, made inconsistent foam and collapsed in on itself. E-mail costumer support to the company went well. They sent replacement foam and after that also did not work promptly refunded the purchase price. It is difficult to contact them by phone, but responded well to e-mail and text.

Compared to another brand of 4-lb pour foam, this brand yields a very inconsistent density. Once cured, I found that part of the foam was very dense (small bubbles) and part of it was very light (large bubbles).

It barely doubled in size at 72 degrees. I had much better success with other brands at 65 degrees. Maybe it works ok at higher temperatures, but I don't have higher temperatures.
