Really fun set!
This is a really fun set! My kids had a great time building this and then plying the game on my cell phone after it was complete! They’ve asked for the other sets as well. Great set for the price

Great set. My kids love the spooky figures and the price on these are great. They also enjoy the app game you can download to play with these sets.

Grandson enjoyed it.
This was a gift for a 10 year old grandson who doesn't do much Lego anymore, but he was excited. He built it immediately and set it up in his room.

Birthday gift hit!
My 10 year old grandson is a “Lego Master” and loved this gift. In my opinion, I feel the Lego items are overpriced and this makes it difficult for some people to purchase these items as gifts for family members.
