I have some ear issues and I'm extremely sensitive to loud noises. We went out to eat the other night and there was such a run on fajitas that the some alarms went off and kept going off until the fire department arrived. I had these in my purse. I would have had to leave and go stand in the cold if I hadn't had these little life savers.
