The BBC made a documentary about the Del Ferro Institute. The followed an English lady with a severe stuttering problem. At Del Ferro, she got the tools to speak fluent, which she applied in daily life situations.
After 3 days, student Ezra already knew exactly how the Del Ferro Method works. He could explain the technique with only fluent sentences. The reason to do the course was because Ezra stammered a lot during lectures. Now he knows that it is possible to do it without stuttering which made him even more enthusiastic during the week!
