Liked the information, but not so much the hype and annoying background music, plus can’t read, pause, or ffw… just locked in to the video. because it was very high pressure and looked scamish, I checked out reviews and was right, apparently. I looked on Amazon: you can buy one bottle starting at $28. Go figure! Lots of other brands out there also. CariPro gets a good rating, might try that. 90 days for $60.
