Hi, Unfortunately the product you mention is not a company or product that was featured or endorsed by The Oprah Show. There are many scams out there that say a product was 'Featured' on The Oprah Winfrey Show. A good rule of thumb is, that if you cannot find it on Oprah.com, then it is not a legitimate claim.
Just recently The Oprah Show did a segment on Internet Scams. Here is some information that has been posted on Oprah.com regarding scams:
