I bought this unit used, (only 6 months old) and I am loving it! It is only audible when it first starts (barely) and then it is completely silent. I have it next to the couch and you have to put your hand in front of the unit to even tell that air is moving. Very nice!It keeps my 90gal right on temperature with 2x175Watt Metal Halide Bulbs and 50Watts of T5.It has a 1deg F on off cycle and is spot on with calibration.Front display has temperature and a light to tell you if it is running (because you can't hear it).I couldn't ask for anything more from this unit but for it to last...100% happy so far!
