I received this as a replacement to the older model (under warranty). So far I've been happy with this unit. It's a bit quieter than the older model (where the air outtake is on the side). I'm hoping this new unit has an overall better design too - since the prior models seemed to not last very long. I also like how this model moved the continuous drain connect to the rear and it's actually angled downward to prevent any 'backflow' leaks.
