Interesting set of 4 double sided tested cassettes with note that says ' for use with active associates only'.. These are training cassettes which describe some how--to's in addition to motivational subjects. Having had numerous professional sales training programs over the years, and having listened to these tapes, I can verify they are informative and worthwhile listening to for Amway or other business/sales purposes - the speakers are sincere and knowledgeable. The Amway organization production is from Network Twenty One in 1998.
