"This set although Lacking in lay features for younger children has some great new and intresting moulds and minifigure prints, such as Harry's, Hermione's and Luna Lovegood's torsos and the exclusive wooden Death Eater training dummy The exploding notices are nice touch and their are also some interesting part usages within the set too, which is why I would argue it is worth the price you pay.
The set can also be combined with the Hogwarts castle is you have some spare connectors (although the box nor instructions shows this) and overall makes a nice little display especially if you have the CMFS Cho-Chang to recreate the Cedric scene.
Honestly, I think a true HP fan will most likely love this. However, if you are buying for a casual fan buying the 4 figure set might be better option or perhaps picking up a different part of the castle if you wish to have more playability."
