It's quite good if you're not consdier $. As this material uses the practical english in daily, for example, splash water...the other material doesn't have.
We bought DWE at book exhibition (7/2011). I am attracted by the 'Play Along' series (that is totally not related to any Disney characters) and our girl enjoyed watching the whole DVD at one go now (that is nearly 40 minutes!) Disc 1 is most useful now. The toys related can substitute her usual ones! She didn't show interest to the rest of series / DWE itself yet. The club membership... We will try attending some parental / play along workshop next month.
