Title: Variable speed breaks after short time
Review: This is my 2nd one of these speed controllers. The first one worked fine for about 5 months, then only powered the fan on max setting. Anything less than max makes the fan hum quietly but not turn. This new one that I've had for a week, lasted about three days before starting the same thing. Don't buy this, spend the extra 30 bones and get a quality fan speed controller.
