Here’s what people are saying about this convenient device: 

“The keychain is really handy. The other day I was at the doctor’s office when I heard the low-battery chime go off on my hearing aid. I knew I wouldn’t be home before it died, but luckily I had a spare in my hearOclub keychain. It saved the day!” 

– Barbara

“The keychain tester has helped so much! We’re wasting less batteries now. We used to change my mom’s batteries every time we visited, but now with the battery tester we know if her charge will last until the next time we visit.” 

– Bonnie
