Well made fun to build !

I had so much fun with this! Great to build focus and patience. Fun and for mature age. Is not easy but is fun and entertaining. Got some delicate parts but is a great fit for a show case.

Really nice kit, enjoyed by young nephew. Lots of hours to put. Skill required. Proud of his realization.

This was my first wood puzzle kit that I have assembled. I was amazed at how precisely all the pieces assembled. The pieces were easy to remove from the boards, and for the most part easy to fit into place. I can tell you that I did not break even one piece of the puzzle during assembly. They do provide extra pieces of many smaller parts, just in case you need them. I did take the advice of other builders and work on top of a towel. Should you then drop a small piece it wouldn't bounce away. The other good advice is to sand all parts to smooth the edges. Also, use plenty of wax when instructed to do so. It seems like a small piece of wax that they give you, but it is plenty large enough to apply it liberally. The puzzle will have to sit level to work correctly. Once level, only small adjustments were made to have it working smoothly. It was a very enjoyable build. I am sure to purchase another!

Overall easy to assemble has a few glitches when running. Working through them. Could use an on/off switch.
