Top Fin® Multi-Stage Internal Filter
Worked good for a while.
It was good in my 10g but as my fish got a bit bigger and produced more bio- load, it kept getting clogged. I'd definitely recommend but for small bio-loads unless you want to keep cleaning it out every other day.

It's an okay filter. If you don't have the money for a decent filter and you need one this one will work fine
Easy to Install
Changing the filter sponge can be exhausting

Not for Betta; may be okay for other fish
The current this thing produces is way too strong for a Betta in an 8.5 gallon tank. I used it with and without the spray attachment. The attachment was very noisy and sent a strong spray of water out. Without it, the water gushed out of the nozzle, which was submerged, and I could tell by the motion of my silk plants that the fish was going to be unhappy. He wouldn't go near it. If you need a gentle underwater Betta-friendly filter, I suggest the Tetra Whisper 10i. I'm using that now with much relief and, I hope, long-term success. However, don't discount the Topfin filter's usefulness for other fish; it might be just fine for something other than Betta. My review is based solely on Betta-friendliness. The two filters cost the same at my local store.

This is a great filter, works fine
this filter works great, but it does take up room inside the tank, which I need for my goldfish, so I am upgrading to a canister filter, and I will use this one in my other tropical tank
all in all it is a great filter for the money
