Overall, every interaction I have had with them has been good. I think that their business model is solid, and they are offering a very important service that no one else is offering as comprehensively. Some of the bad reviews may have come from a time when they were growing rapidly, but I suspect from my experience that they have worked many of the kinks out. I think everyone should use them, if only to save money and help the planet in the process.
