Works great now I know if they are good or not

I love it and batteries check every time and everyday and love it

Tester arrived on time and wrapped very well. Got this for my mother. She's very happy now she can test her batteries instead of changing until she gets a good one. Loves because it is small enough to carry with her. It's real easy to tell if batteries are fresh or not.

The light signal on this tester determines battery life. If it is very bright then you know it is good. If the light is dim and flickers then it is time to change the battery.

I got this battery tester for my Dad to use. I am able to use it easily to check his hearing aid batteries, and it works well. The only drawback is that my Dad has difficulty holding the tiny battery, positioning it correctly, and pushing it into the test area. This keeps him from being independent with checking his batteries. If the person who needs to check their batteries has reduced ability to manipulate small items, you may want to get a battery tester that you lay the battery on and slide it to test it. Otherwise, this battery tester does what it is designed to do!

I used one of these for years, misplaced it, and was really happy to find it here! It took two days to get here, and no shipping charge. The price is much lower than for other hearing aid battery testers I've found on the Web. I don't think you can do better.

Have nothing but good to say about Diglo. Order correct, delivery on time and product was what I wanted.

So far it works like a charm. The battery tester seems to work and I haven't lost it. I had lost 2 previously within my first 2 weeks. Convenient. But, the reason I wrote too early to tell is that I do not know if it will work in a year or 2 or 5 or 10. I bought a spare in case I lost the one I have. Probably worth the price. I gave it 3 stars because it is too early to tell.
