I installed this kit in our toilet room, on off no speed control, 5 years & 40k miles ago. Less noise than the cheepo tiny rattly $3 fan we had originally but way more than the fantastic type. If you would like to run the fan for general ventilation, I'd bite the bullet & go for the better fan instead. If it's an occasional short duration run fan then this one is great. Good volume. I thought the plastic gear to raise the hatch would have worn out by now but it hasn't.
