Susterra propanediol vs. glycol

    Hello All, 

    I grabbed a brochure from these guys at CBC, touting a non-petroleum glycol alternative that is "made from renewably sourced materials and certified by USDA BioPreferred program as 100% bio-based." They also claim it can be mixed with glycol as the system is topped off, so no need to dump all of the glycol and start over.

    Has anyone used it and have any feedback? Without listing price, how does the price compare with glycol? 

    Cheers,
