This is a truly gorgeous set. I purchased this for my husband for his first Father's Day, and we have had so much fun putting it together. The set is a bit expensive, but it is essentially three buildings in one, plus a few small stands (cauldron stand, an owl stand, and a hat stand). The details in this set are incredible; Potter fans will be excited to see how much care was put into the design. For example, there are small copies of the Quibbler, the Daily Prophet, and the Marauder's Map for the characters to carry, and there's a wanted poster of Sirius Black for the side of Ollivander's. It's actually a great value for the number of items that are included, and it's challenging enough to take a couple of days to build.
First, there's Ollivander's Wand Shop. This is a two-story building in green, tan, blue, and black. The window design is incredibly well done. Inside, you've got some wand shelves, a desk for Ollivander, a ladder to get to the second floor, and a few other surprises. Both the inside and outside are well detailed.
Second is Borgin and Burke's, a set in gray, black, and green. Despite the fact that this building is actually in Knockturn Alley and not Diagon Alley, I'm really glad it was included in the set. The building contains a number of surprises, not the least of which is an actual vanishing cabinet and a Floo entrance that spins. The attention to detail is remarkable. That being said, I would have liked to have seen a few more "dark objects" to scatter about the store--maybe a hand display or the silver and opal necklace, for instance.
Third is my personal favorite piece, Gringott's. It's a beautiful white and gold building. It includes a desk and a vault, as well as numerous little touches that make it seem like a bank. It also folds, which is pretty neat.
Minifigures include Harry, Ron (in a cute little sweater), Hermione, Fred and George Weasley, Mr. Ollivander, two Goblins, Hagrid, Lucius Malfoy, and Fenrir Greyback.
Overall, I think Lego outdid itself with this set.
