I lub me the Red Sea Nano. Paid 9 bucks for mine, still pumping strong for over a year in my 5. The flow control valve is a godsend for small betta tanks.
I'm actually about to replace the one I just bought already.
My betta got his fins sucked up into the intake and it blows him around if he goes on that end of the tank. I have the thing turned down as far as I can. He just has such huge fins that it isn't working out.
I'm going to try a Tom internal filter. I have one on another betta tank and it has worked very well.
But if ya'll want to see what I did....
I dumped the bigger white sponge, I bought a pond filter carbon infused pad (12x12") and cut it up into small sizes that fit in the Azoo. I got 24 out of the pad and even had about 24 little smaller pieces that I can use in my Tom mini internal.
I then dropped a few tiny bio balls that I had into the bottom just to provide some more surface area. It seems to work perfectly (except that my betta thinks it's too strong), the 3.4 gallon tank is staying crystal clear.
