Every battery in every package has given me reliable service. There's never been a bad one! And I like the efficient, compact package. It slips easily into my wallet so I always have extra batteries with me.
Sorry to say that I wanted these batteries to last longer than the ones I got from my audiologist but it is not the case. I placed one battery in the left device on 2/12 and had to replace it on 2/17 and the right device on 2/13 and replace that one on 2/18.
I am very unhappy with your product. Please cancel any future orders. t least 10 times I have had your batteries last less than a day. It has caused me much stress. It has happened on several orders now and I think there is a problem with your quality control
I tried several kinds of (cheaper) batteries before contacting Rayovac and was not happy with them at all, they did not last long at all. My company charged very high prices before they closed. Now I buy direct from Rayovac and am very happy. My new company charges $20 just to clean my aids which is exorbitant for a few minutes of work!! I would never buy batteries there. Thanks for great service and great batteries.
