I used the machine for knowledge. It works just fine. It produces energy like it is designed to do. The knowledge I gained is good enough to make a bigger one. I'll change the way it works for future reference.
Amazingly precise milling, powerfull enough for experimenting. Perfect for the electronics hacker, gear head, or simply curious about science
This is a beautiful, perfectly machined, perfectly operating piece of kinetic art. The price is exceptional for what I received. I could not possibly expect more.
All packed very well. Had them all running within and hour. They work very well, are built well, and are very ornate!
Awesome little engine! This is a very well built product. I bought this for my 11 year old nephew who likes science and anything with an engine. He absolutely loved this gift. I like it so much. I highly recommend!
