This is a very impressive set and my first purchase in the Monster Fighters series. Before I really get into it, I have to say that I HATE stickers, and this set has a dozen or so, all glow-in-the-dark. Stickers aside, there is a TON of great things to like; details like the trapdoor above the spikes, the bookshelf, the spiral staircase, and the minifigures. The minifigures are especially great because the vampyres have glow-in-the-dark two-faced heads, and both monster fighters have either a robotic arm or leg, which is a really nice touch. The vehicle, the net-launching car, is the first part to build and was very easy to build and impressive. The rest of the castle was not too difficult to assemble either and castle and car came together in about 3 hours total. The only con is, in my opinion, the stickers. I've not had good luck with them in the past, but when I shone a flashlight on them and turned out the lights, I kind of saw past that.
