Ever grow with Sensi Pro from Advanced?

Just wondering if anyone's every grown using this stuff. Stubbled on a website called urbangrower.com and he uses this stuff from advanced nutrients. I looked on the net trying to find a store that carrys the sensi pro but could only find other advanced products. From one of the shows they mix up the sensi pro and it was super easy, they dumped the premixed bags of nutes into the resevoir and it was even already pH'd and correct ppm for various stages of growth.
