Sound like BS to me. In cases where it "works" it probably does so by being uncomfortable and thus interfering with how the person normally sleeps - perhaps causing them to move around more.
I wanted to see if there was any basis to the "scientific" claims, and found this from a thread on another forum:

Unfortunately the original is gone from the ASA site, otherwise I'd have linked to the original. I don't know why they only seem to retain records for a few years. It seems like keeping that information in the public domain should be part of their remit.
As for the money back guarantee, it likely involves a lot of unwarranted hassle, plus the cost of return postage. They also insist that you try for at least 2 weeks. By that time if it hasn't worked, they know most people won't bother claiming the refund, so they aren't really going to lose money, especially compared to the extra sales gained because of it.
As for the whole "meridians" mumbo jumbo, this is among the more tenuous aspects of Chinese traditional medicine. Even my taiji instructor doesn't believe in it. Pressure points are certainly very real, but the whole business of energy lines connecting certain extremities to your heart, liver, etc., is at best "unproven". I say this as someone with enough of an interest in the subject to own a couple of books by Erle Montaigue. Doesn't mean I believe every word of it.
Also, while there may be a few "testimonials" floating around, assuming that most of them aren't fake, anecdotes are not scientific data. There's apparently a "scientific" study that they themselves funded, but I couldn't find the actual paper anywhere so remain highly skeptical of its findings. The only thing I could find on the Aspen research site was a page showing how much PR their "study" had got their client:

No link to the actual published paper. Does this seem like a reputable scientific body, or PR agency masquerading as one?
