I've been with them since 2015 when they launched their private beta version of the software. Since then they've been extremely helpful and responsive to any questions I've had about how to use their product. It's a great product for people who want to get back to sleeping, like me! A little hard to find information online if you don't know where it should go or what it does. That said, I think there needs to be more information available regarding using this tool (aside from "go here") as it seems pretty complicated. But overall very useful - my sleep improved dramatically after starting using it regularly.
