Exceeded my expectations.
The directions in English are a bit rough, but the actual engine is great! It's definitely not silent. I should try lubricating it. Very entertaining and does a good job of depicting the stirling heat cycle in action. Very happy with this well-made product and will consider buying more as gifts for my geeky friends.

Great little valves! I came back for seconds.
These have performed beautifully for my low pressure pneumatic application. When they would close, I found their collapsing magnetic field would surge my Arduino's ground reference, causing it to reset. To mitigate this, I scraped away some of the positive and ground wiring insulation close to the solenoid and installed a flyback diode across the exposed conductors (I actually used an LED so I could visually see when the valve would close...they have yet to fry, but probably won't last super long. Easy to replace, though). I'm very happy with these compact, reliable valves. They get hot when open for a long time, but not too hot. I like them so much, I ordered four more directly from TEMCO's website (which is cheaper than this online auction site).

Not perfect, but it'll work.
Definitely a pain to get it in there. Had to wrestle to make it fit, but perseverance paid off. It bows a little bit toward the tire along its bottom edge, but doesn't interfere with the rubber. Almost seems like it's slightly too large for the wheel well, so it's a little smooshed in there. Isn't perfect, but will get the job done and doesn't look too bad. I'm overall satisfied.
