Ive never seen a peristaltic pump for under $100 so I didn't have high expectations on this one, but it turned out to be a very solid well designed German made unit, not Chinese ?! Totally silent when running. At 10 RPM I think it will last a very long time. It has a Santoprene internal hose and compression fittings that perfectly fit the 1/8" I.D. silicone airline hose I'm using to deliver pH adjust chemicals. It also includes two mini check valves that can be installed inline to prevent backward siphoning but are optional. It has no problem drawing fluid up two feet from my chemical container. very pleased. Cheers.
