Rated 1 out of 5 by AllieH It works fine, but is noisy.
It works perfectly, but is so insanely loud, you'll immediately go get another one just to make the noise stop!

Rated 5 out of 5 by CrazedWithFish Good product
It is good for a traveling with live fish in a bucket. It is loud but that is because of how it is made. I have seen the same design on almost all battery pumps. A motor spins a handle that move the rubber disk moving air. Since the handle isn't balanced of course it will make a humming sound.

Rated 2 out of 5 by Taro Good idea, needs work
This pump is LOUD.
The fact that it's battery operated is a plus and makes it good to have on hand in emergencies, or if you need to transport your fish.
I bought it with the latter in mind, and was going to use it on a regular basis as well, but the motor's hum is just too strong. I can hear it from two rooms away!
A good emergency purchase, but wouldn't recommend regular use.
