This Stirling engine took a real long time to come in the mail so when it showed up it was a real nice treat I was excited. Went to use it and it works perfect and spins real fast with very little heat. The only thing I would change us to be able to see the piston inside. I thought it would come like that. But it's still really cool and worth the extra money and the wait. I gave it 4 stars because in my mind 4 is the absolute best and 5 stars is for those rare things that just absolutely blow your mind which are rare. Honestly I would probably give this 4 and a half stars. If I ever have kids I will give it to them. I'll probably order more things from this company someday.

Absolute "Best in Type" design.
Excellent design! 1st, the use of gears in lieu of a single shaft with 90 degree trailing offfset. 2nd, the 'unscrewable' cylinder which makes cleaning a cinch. 3rd, the use of ball bearings. 4th, the elegant method of attaching the 'hot side' that enables the thinest barrier to heat transfer. Superb! I wish that there was a way to communicate with the designer(s) via email. Do suggest shipping with a parts replacement list. Job well done folks! Thank you for a wonderful product.
