This went off in the middle of the night after my husband and I had had it for several years. We had to look up online the directions because it didn't have a clear beep for a warning and for a battery replacement. It was ridiculous. I would not recommend it. I want one that clearly tells me when to vacate the house and call the fire department.
A:
Negative
