Great But LoudMay 04, 2009
By Ambria Lee
I bought this since I live in Florida and the storms that come through here can leave people with no power. At first I had my doubts about this. So this is what I think of it.
Pros: small, uses D batteries, last a long time, works when power is out and delivers what it is supposed to do.
Cons: Loud. this thing is loud but I have an aquarium cabinet and I put it under there on the shelf and I never heard it when the power went off. So if you have it out in the open, it will be loud. Suggest placing a cloth or something underneath it so it will cut down on the noise.
Overall, I love it and will not be without one. I only gave it 4 stars because it is so loud. The rest is definitely a 5 star.

Peace of mindMar 28, 2011
By Imhonored
This product does exactly what it says it does. It is a good system for an emergency aquarium pump that cuts on automatically when the power cuts off. Very convenient when it happens while you are at work or away from the house. Some have said this model makes a lot of noise, but I do not think the fish will complain that they are getting airflow in an emergency. The noise is not that loud, IMO, and it can be muffled if placed inside a cabinet, such as those that most aquarium stands have. It takes two D batteries, not included. The tubing that comes with the product is only about 12 inches in length, so for my system, that was inadequate. But it accepts standard tubing that you can purchase at your local pet store. For a few bucks you can get about 6' of tubing.

 Great Product!!!Jul 06, 2010
By Aquarist
This is the second one I've purchased. We did have a power outage during the winter in which we lost power for almost 3 days. This worked great to say the least. I have a battery back-up system but with no power there is not a way to recharge it so when it went dead these keep running because all you have to do is replace the D cell batteries which I didn't have to do...very efficient!!! It can be a little noisy when it is running but definitely something you can live with as it is only temporarily. You won't be sorry owning this product!!!!
