Eheim Universal Aquarium Water Pump 630GPH

Very quiet. Had it running for about 1 year.

No problems at all. No noise.

Easy to clean.

Just need to watch out for the small black ring around the shaft. One of them fell off (and I could not find it), and I had to buy another full shaft.

I got this eheim to replace my mag 5 that was running virtually silently for several years as a return pump for my aquarium sump because the mag 5 started to vibrate very loudly after I used it to drain my basement after a flood. The eheim is actually louder than the mag 5 it replaced. I think I may have just received a bad pump, but would think that if I paid over twice the amount for the eheim than the mag 5 that quality control would be better. The eheim is a very strong pump, however, I just wish that it was as silent as the reviews state.
