The engine is nicely done, very well and sturdily build. It runs smooth and is nearly completely silent. It is worth spending a bit more to get this model than the cheaper low temperature engines.
This is one of my favorite engines to show off, beautifully built with high quality parts. Such a simple design will have you gazing out appreciating how well it works. Really is nice and packaged good so no damage on arrival, great price too. I highly recommend this to anyone learning or just adding to your collection.
A very well made and enjoyable little toy.
