The hose colour didn't tip me off, but when I spotted the res... first thing came to mind was "American beer". The second was "Urine sample". Sry.
I'm a little curious - "dead-silence"? Including the pump? Any comparisons you could offer? Those YL's look like they're running at 12 volts, but which model are they? And is the pump quieter or louder than them?
