The thing itself is well built and probably does its job well, it certainly feels like it will. However, the design has a pretty serious issue, that you should be aware of before ordering: to fill the container, it only has an auto valve (Schrader valve), and there is very little space around the valve. This means that if your pump, that you will use to fill this compressor with air, has a large head it will not work at all! I have a nice Lezyne pump with a dual valve head, and that is impossible to fit on this compressor. So I now have to go look for some sort of valve extender hose, or buy a different floor pump to be able to use this compressor.
