Pros & Cons

Pros

Only assembly required is the little 'alcohol burner' with this setup the flame is closer to the piston than with the tea light and it runs very fast. The led is a nice addition as it adds another layer to the setup. The manufacturer gives an extra he... Read More

The durable, all metal design with a touch of chrome makes this really appealing. It is nicely machined and balanced.

Everything was packaged with great care. Nothing is loose or rattling. Both the original package and replacement order were well protected with bubble wrap and arrived undamaged.

Cons

Bought 95% clean burning denatured alcohol fuel. It's a real shame that this product is made so well but with bad quality materials. Second engine was defective.

Quality

Appears to be of very good quality

Price

For less than 2 i also purchased 91 rubbing alcohol as fuel as recommended in other reviews and it worked well

This is a super cool little engine for the price

Hard to understand how anyone makes money at this price

Purchase 91 rubbing alcohol at your local meijer for 6

Shipping

Sunnytech immediately sent three replacement burners from china with a bonus replacement cylinder and three extra leds

They kept me informed of the order and it arrived within two weeks from china

I just received my stirling engine in the mail

Packaging/appearance

Both the original package and replacement order were well protected with bubble wrap and arrived undamaged

It is absolutely beautiful and came with a spare glass test tube led and rubber band

The pictures on amazon show a blue belt band connecting the engine to the generator but mine came with a red one already on the... Read More

This came already assembled in the box with me only having to fill the fuel glass and put the wick inside it

Competitiveness

The alcohol burner is too small sunnytech sells a much better unit for 10 bucks its shorter and wider with a much thicker wick

I have not tried lamp oil yet but it may be a good as well as a safe alternative
