Product review (5 stars): Very happy with this purchase
Very happy with this purchase.  My smoke detector used to go off every time I would can from the steam.  Hasn't gone off once since we installed this.  As others said, a little loud but but doesn't bother me at all. Much quieter than a smoke detector.  Install was not difficult but needed two people. Dont really use the light so I cant help you there. Clips to hold faceplate not great but doable.  Still, great purchase.
