Had the EX45 for a year in an overstocked grow-out tank. Very quiet, no priming issues with this design. The filter "cartridge" is ok, I just cut my own floss to use. Not bad biofiltration. Good value for price and durable so far. Haven't had to clean the impeller in six months, it's still moving a lot of water! As good as any HOB I've owned and quieter than most.
