"This is way superior to the undergravel filter I used to have.The plastic fastener broke that holds the tube, but it still works. Once it stopped working for me, but all it needed was a good cleaning to get it going. It makes some noise, and filters that come with tanks are usually quieter. It also isn't a very good color and doesn't really complement my 2 gallon betta tank. If I could make the choice again, I would rather get a tank with a good built in filter rather than buy this, but it works. =)"
