Very well made. Instructions are clear and concise and when put together, makes for a great working display piece.
One of the easier ones to assemble. Was fun to do and looks awesome!
Putting this kit together was incredibly enjoyable for me. Once it was all together it worked very nicely. If you like building things, puzzles, or just amazing machines in motion this is a great kit. Once you get it make sure to follow the instructions very carefully, though, in order to make sure all the parts line up. Also be sure to wax the meshing area on gears BEFORE you put it together. This is very important. Aside from following the basic instructions I only had to sand down one tiny bump on a rotating part for it to work flawlessly.
Went together very well, looks super nice and it works so all the dots for this 3d puzzle were ticked perfectly.
