The digital heater is super quiet and emits a gentle heat.  The panel doesn't get hot and stays cool to the touch.  The controls are easy to use and include a timer function, delay start function and the ability to adjust the temperature.  The one feature I like is the 'anti-freeze' setting which will keep the temperature at 45 degrees to not allow freezing.  This is great if you have an area that is not heated, or you need to keep temperatures above freezing for some reason.
