My boys were so excited when their grandma and grandpa got them this as a gift. We usually did those chocolate advent calendars so this was a nice change. They were so excited to open a new door each day. It felt like we were spreading out Christmas a bit because they were getting little gifts each day of December. They had a lot of fun with it. It also has a little cardboard town that comes down so there is something to play with the Lego items on. There were some little figurines, Christmas items, Lego city things and more. They would just put it back in the doors after they were finished playing for the next day. Then they would pull them all out again and play all over with whatever the new item was and with the ones they had already opened. I know that these can be a little expensive, but we found ours on sale. We were able to get ours at a toy store. I would definitely look into these again if they came up with some different ones. I know that there was a Star Wars advent calendar for Lego as well. These are such a fun gift to give to someone!
