Great products. Even better company. The customer service is FANTASTIC. Fred walked me through the whole process and they were even available on call over the weekend for questions as they popped up during the project! Don't even bother with the kit that you can get off the shelf at Home Depot. It doesn't work as well, is way more expensive, and doesn't come with the helpful service.
