Works with all types of hearing aid batteries. Easy use with size 312, 10, 13, and 675 hearing aid batteries. Place battery on metal testing surface, push battery against the tester, and accurate results will show labeling the batteries as good or bad.

It really works!
When looking online for a hearing aid battery tester, I admit I was rather skeptical of what I was finding. My Mom is 91 years old and I needed something that was easy to use AND easy for her to see the digital readout. We were both pleasantly surprised by this digital battery tester. It's easy to hold the battery in place over the + sign above the arrow and read the digital display. The unit will handle batteries of various sizes too. I would recommend this product.

Product works but it turns out to be somewhat unnecessary.
As a newbie to hearing aids, I thought I would be able to use this tester to squeeze out every last second of battery life, thereby saving a bit of money. Turns out that the hearing aids themselves give you a 30-minute warning when their power is about to expire; after that, they simply stop working. That may not be the case for other brands of hearing aids (mine are Phonak). There is nothing at all wrong with the battery tester; it works exactly as advertised.

I like that I can keep extra batteries on my keychain ...
I like that I can keep extra batteries on my keychain so when the ones in my ears beep I have new ones to replace them with.

Not useful
Most hearing aid batteries now are hermetically sealed from the environment, and begin to work (and decay) from exposure to air. This is not a useful device any longer.

I've found that I don't use this product very often.
This product does what it is intended to do but I have very few times to actually put it to use. I wish I had saved my money.

Perfect
It was purchased for someone who is 100 years old. When she thought the battery was dead, she would put in new ones.Now with the tester, someone can check all the batteries that she just takes out and let's sit.

Piece of crap
This is a worthless purchase. Doesn't work. There are no instructions as other reviewers noted but it's easy enough to figure out. You place the battery on the plate and push it against the metal arm and the display is supposed to give indicator bars to show the battery strength. The unit I got faintly showed a few bars with a brand new battery and then never worked again. I don't recommend wasting your time and money on this at all.
