The Pro's about it are:
For it's size it has a large filter volume, you could substitute Hagen/Aquaclear filter sponges for the media. Not really expensive.
The Con's about it are:
It has the power-head in middle the aquarium tank intake, sort of clunky and would make hiding it a challenge for a small tank.
I'm assuming that's in centimeters? So roughly, 7.11 US gallons in volume?Hiding is no problem but give it a good flow in the tank it is a 30x30x30
