Grandchildren come to us, with parents, every Christmas. All 4 LOVE Lego's . The 3 boys loved the Motor Works. There are Lego pieces all over each and every table in the house. The NEW ones as well as the ones from previous years. They do them over and over again, enjoying the making of them every time. They liked the fact that the Smithsonian Motor Works was a little different than the other ones they have done.

If I could give it zero starts I would. My son saw this months before Christmas and specifically asked for it. I started putting it together on Christmas Day and it's still sitting on my table unfinished and not working correctly. I contacted the customer service people at NSI International right away. She offered to send replacement parts but as I explained to her there are not any obvious defects. It just will not run like a motor. It will keep getting stuck in the same spot and sit there and grind until you help it by hand. I repeatedly asked for someone there to help troubleshoot and sent them a video of the problem but they basically just quit answering. Don't waste your money on this because it's very poor quality components and no matter how closely you follow the directions it's not likely to work correctly. I've read that others have had the same issue. A huge disappointment for me and my son.

The engine parts were plastic and my daughter had to scrape off some of the edges for the pieces to fit together. She also had a problem with the exhaust valve. The parts would not stay in place and we may have to glue them in place. Otherwise the model is a good learning tool. My daughter learned the names and functions of the parts as she assembled the engine and prepared it to work.
