I have a family member that uses it. I'm not impressed. Don't get me wrong, they are probably the "most above board/least crooked investment advisor" he's ever used -- so in his case it is a good thing. And I think there are lots of people that need hand holding and a sit down chat every 6 months or so to provide feedback/direction.
But, while he looks at what they do and sees some positive growth, I look at it and think "holy crap... with as much as you have invested and THAT is the return you get???" He would have been much better off had he just bought a VG 500 index fund and stopped there.
