So far so good although the "Hi" fan setting is rather noisy. I would recommend that the manufacturer upgrade the fan to a more quieter one considering the price commanded. The "low" fan setting is okay.  The unit puts out sufficient heat and I particularly like the "on" & "off" temperature cycling feature that saves on the wear & tear of infra red elements as well as electricity usage. We shall see what happens to the heater as it approaches the 3 year warranted period.
(We previously had an old 2 element 1500 Watt Molnar infra red heater that lasted for over 25 years up until this year. Too bad they don't make them anymore.)
