Title: sometimes yes sometimes no
Review: We have had several of these over the years. Lightening or any erratic electricity seems to take them out pretty easily. Also, when you buy a replacement it may or may not work. Sometimes we have to buy three or four to get one that works for a while.We keep trying because we need the sound alert in the house that someone or something is coming.
