50 YEARS AGO YOU COULD ONLY GET A PUMP LIKE THIS FROM GERMANY!!! AND IT WAS BIG BUCKS $$$$THIS LITTLE INEXPENSIVE AIR PUMP IS JUST AS GOOD AS THE GERMANY UNIT THAT I PURCHASED YEARS AGO!!! I STILL HAVE THAT IMPORTED PUMP... THIS ONE IS JUST AS GOOD... HOPE THAT I'M AROUND FIFTY YEARS FROM NOW TO REPORT THAT IT LASTED AS LONG AS THE IMPORT????? "LONGEVITY" ??? WILL HAVE TO WAIT AND SEE.... THAT GERMANY PUMP I'VE HAD TO CHANGE THE RUBBER DIAFRAME ON A FEW TIMES IN THE LAST 50 YEARS..........

The air pump for my 20 gallon tank was super loud, so I wanted to find a really quiet one. This one fit the bill. Nice and quiet, as far as air pumps go! I keep it on the lowest setting, and it produces enough bubbles out of the air stones I have connected.

I got this for my sponge filter an bubbler for my new tank and i notice that if u don’t used both hose inputs that it makes a super loud vibration noise . I just put a bubbler in on the other side and it cut down on the sound ALOT. It does has a knob that’s supposed to adjust the flow but it doesn’t make much difference at all, the flow is still pretty strong but that’s find for my filter it’s just the bubble I’m gunna have to cut the tube an put a adjustment knob on it to reduce the flow more

Works well. The tubing was kinked and had to be replaced. Other than that it just right.

Bought this for a small scale hydroponics experiment, and it works great doing what I need. Been running constantly since I got it with no issues and cannot even hear it.

Quiet and works great

It's compact and serves my purpose

Pump worked well new but only lasted 5 weeks and stopped working.
