I think the greatest thing about this puzzle is the fact that the parts are laser cut and very, very precise. I am 87 years old and this was my first try at something like this. Puzzle went together and worked as it should have. One Note: Directions are a little vague in some areas but just take your time and think it out and everything will work out. I used a magnifying glass to enlarge the pictures and this helped a lot.
