  • not durable enough for younger students
A cool idea but a poor execution given the $40 cost. Mine arrived damaged with a bent crankshaft that prevented smooth operation. I think that the materials and design were 2nd rate. I was going to use in a class room setting, but I doubt this will hold up with kids and getting dropped. The cam timing seemed to be off relative to piston - and there are no timing marks on the crank and cam gear that I could find. It just looks and feels cheap and fragile. I returned it because of the shipping damage and did not replace. All instructions are in Chinese only, but you can figure it out. I would buy another one if it cost $15. Less crying when it breaks. ... show more

Had to repair to make functional. No English instructions. Not worth the price
