My daughter finished this in about a day and a half. I had read Cbill's review and we got some fairy lights to put in it. It is in my grandson's room and it's lit up at night for him. He loves it. She had some issues with the top most levels of it. There seemed to be a lack of support for some pieces and because they are small other pieces dropped in to the lower part because they were hard to hold on to and equally hard to fish back out. It did come with quite a few extra pieces. All in all, worth what I paid for it, for sure.
