Rated 2 out of 5 by mocket weak pressure, misleading gallon rating
This item designed for 20 gallon in weaker (1.8 watts) than the Whisper 10 (2.2 watts). A little noisier, but not bad. Whisper has an air filter which makes air stones last longer.

Rated 1 out of 5 by SmudgeTheGoldfish Waste of time and money
I bought two of these Grreat Choice air pumps, one in the 20 gallon and one in the 40 gallon size. Both pumps died within a month.

Rated 5 out of 5 by Ataridude It really is a grreat choice.
This air pump is so cheap, I was afraid it was going to be one of those "you get what you pay for" scenarios. I was delighted, however, when I plugged this in and it made hardly any noise while creating a ton of bubbles. I am very happy.
