This is great for a small aquarium say 5 gallons or under. It's a perfect miniature of the bigger filters! The filter cartridge is very small, makes me wonder how much it can hold

Great for small aquariums
So far this seems to be a good little filter. My only complaint was that the instructions were not very clear and they made me think that I had to purchase additional items to make it work. But everything was included and so far so good!
