This set is a fantastic set for play. The build is a lot of fun, and we don't have to worry about stickers. We also get two minifigures (Harry Potter and Ron Weasley) with Aragog and a tree. The tree has a mushroom and a spiderweb with a lot of little spiders. There's also a hidden flick-missile, which will shoot out another spider web. Aragog looks very cool as well. You can move his legs, eyes and fangs, and he looks very scary.
 
All in all, this set is a great little set and I would HIGHLY recommend you to get this. You can find this set on eBay and BrickLink for sure.
