Bought this for my daughter's third birthday and it was a hit. Unfortunately I think this item is more appropriate for 1-2 year olds although the recommended age is 3+. It's so weak and I'm having trouble connecting the tunnel to both the lock and the ball pit. I saved the castle after the party and now it's their hangout. The lock is age appropriate but I might buy it separately. I will probably use this again for my 19 month old daughter for her second birthday. It's a great alternative to birthday fun when you're stuck at home!
