Any opinions on Superthrive?

Has anybody used or have an opinion about superthrive (http://superthrive.com/)?

It seems like one of those products that might work well, but sucks at advertizing.

I use it on all new plantings/transplants and on any trees and shrubs showing stress. I have a friend that is quality control manager at the largest wholesale nursery around this area & he swears by it also.

I have had people tell me good things about it. I have no first hand knowledge. I have used it once on a high stress application, but I don't know how well it works.
