I've only had the chance to "test" this, as it is my daughters Christmas present, but from what I've seen so far it seems to be really good. I thought it was really cool how the Move remote is transformed into a magic wand (on screen), which really adds to the elusion that I am really a wizard (hahaha). You can also choose what Hogwarts class you belong to. I chose Slitheryn (spelling?) ;)
So far it seems really cool. The spells were good and easy enough to pull off. Unfortunately I had trouble remembering some of the movements when I was put to the test, so if you're like me and a little forgetful, just make a quick note of the movements on a slip of paper before your tests start.
All in all it's very enjoyable and highly recommended for fans of the Harry Potter series.
