This is a well designed product, with a few faults. Some adjustments will have to be made. Although it says no glue needed, you will need glue. Assemble it without glue first, then you will know where you need glue. The biggest problem I had was in assembling part 13 correctly, and after placing it, having to raise one end to allow it to work properly. You must pay attention to the instructions exactly. I found myself taking a few pieces apart, because I assembled them wrong. There is also a piece i had to add, because the steel balls did not fall onto the track at one point. You won't be able to assemble this quickly. The fun is in making it. Don't be fooled by the video. There are no lights. I would not advice this for young kids, because it takes patients and concentration to assemble properly. The good news is this is not like the old balsa wood airplanes where you would have to use a knife and pieces broke. The parts come out easily without a knife if your careful. Yes it's pricey, but overall well made. FYI, all the A parts are on one sheet of wood, and all the B parts on another....etc.
