“This is LEGO's first version of the dark magic store (a second is included in the 2011 set 10217 Diagon Alley), and the dark colors of the set hint at the shop's connection to the Dark Arts. The chimney has a function that causes Harry's minifigure to fall into the shop... More through the Floo Network, as seen in the second Harry Potter movie. The store also has transparent black glass.”

“This is a pretty darn good set. It has lots of rare and useful pieces and colors, some great minifigs, and an excellent design. The only real downside is that it doesn't have wands or capes, which could make it a bit more interesting, but if you're a Harry Potter fan,... More supplying these shouldn't be a problem. I say that if you're willing to pay the price tag, go for it! I don't think you'll regret the purchase.”
