Just thought I'd put this up incase anyone is interested.
I personally really like this filter I have it in one of my 5 gal
betta tanks and it is absolutly silent. You can adjust the direction of the spout almost 360 degrees to have it face where-ever you want in the tank. However it doesn't have an adjustible flow, and it does generate a fairly stong current though the whole of the tank. However where you put the filter and the direction you have the spout facing will change the strength of the current that you'll see in you tank.
