I love that the gum has NO aspartame or Ace-K. That's why I bought. However, the flavor of this gum has NO lasting power whatsoever. I started chewing a piece as soon as I bought it, and literally about one minute later, the gum was completely devoid of flavor. I don't know how it compares to Glee Gum (another gum without aspartame that I want to try), but this was very disappointing. Three stars for no aspartame and Ace-K though!!
