Can anyone provide a review of these interactive wands? How many different "stations" are there to use these wands? Just in the Harry Potter section of the park, right? Are there places to use them in both parks?

How interesting are these activities?

My son bought one on a school trip a few years ago . . Trying to determine if he has aged out of it or not. (Bought it age 12, now almost 15) We are going to WDW for the first time in 4 years, and this wand might be the only reason I leave WDW for a day and head to Universal.

Thanks for your input!
