Several days in a row, my inability to hear has been tracked down to the receiver coming out of my ear. In each instance, the hearing aid was beginning to fall off as a result of the receiver issue. Each time, I was pleased to know that the hearing aid would never really fall off, but it was starting to be a nuisance. When you can't hear, it's hard to know when the hearing aids are not working as designed. Finally, after some detective work, I realized the dome was failing and that caused it to not fit properly in my ear any longer. New dome, problem solved. Without the Safety Aid, the hearing aid could have fallen off while I was sorting out the issue! So I was indeed saved by my Safety Aid®!
