Rated 4 out of 5 by GuppyJack Decent product for the price
The air pump works great with the Top Fin air stone disk I got. It's in a 10 gallon tank and produces plenty of bubbles. Noise is relatively low as well, not much louder than the filter. I recommend the air pump 20 in the 10-20 gallon tank.

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.
