Review: Very rewarding, needs care and patience but everything goes together as it should. Quality item - Very well made with clear instructions. Need to make sure all burrs are removed and gears etc. are waxed and tested before moving on to next assembly instruction. Quite complex but very rewarding to do and works beautifully if care is taken with the assembly. Highly recommended.
Review: Well made - Assembly was medium to hard so make sure the instructions are read carefully and make use of the QR code videos. It works really well when finished and if pieces are not quite right, the other pieces will compensate. Looks really good when finished.
