This by far the best money I've every spent on a DVD or toy for my three boys; 2, 3 1/2 and 5 yrs old. Before this DVD my 5 year old new a handful of letter sounds. Now after watching this for a few weeks, as well as Talking Words Factory, he knows every letter its sound and is spelling three letter words. It is truly amazing. My 3 1/2 year old is learning letters and sounds and they both would rather watch this then Spongebob most times. Now that is amazing!
