Rated 1 out of 5 by Charlie70 Whisper 30-60 broke after 4 months
I purchased the 30-60 air pump 4 months ago, and the interior piece that holds the "replacement parts" broke. It has been sitting in one place since I bought it, I didn't move it or drop it. Now I have to buy a new pump.

Rated 5 out of 5 by Charlene1 These are super little pumps!
I have two of these pumps purchased recently, one for a 20-gallon with two undergravel filters and an airstone, the other for a 5-gallon hex with an undergravel filter and possibly more aeration at a later time when I add fish. They pump all the air that I need with air to spare. I hear of people having problems with noise or early failure, but I believe the important thing is to make sure to have a relief valve to bleed off excess air and make sure your pump is ample size for your needs.

I have one of these with my 10 gallon tank and I can't here it, but it produces good amount of bubbles too.
