I've brought it since my daughter was born. It has been 2.5 years. She loves it and use it very well. She can talk with me by using simple English. Compared to my friend using English Time. She is still can't talk in English.
I bought it in 2004 when I was pregnant. My girl has finished using the set, and just left aside.
Her English is pretty good, but not sure if all contribute by DWE
