The batteries do not seem to last quite as long as some of the name brands but for the price your still ahead. The packaging is not user friendly. The install tab is too small.We pay more elsewhere for another brand. The ease of use in the rotary 8 pack and larger install tab is worth the difference to us.Good deal if you can work the packaging.

Difficult to remove from package. Only lasted four days per set.

Packaging is horrendous! Takes forever to get each battery out of the multi layer plastic.

Very hard to get out of package.

Package is very hard to open. There needs to perforated panels to separate into smaller amounts.

We do not recommend these. My husband uses them in his hearing aids and he went thru this pack in 5 weeks.

Tried 2 batteries and they only lasted 3 days. I have been wearing hearing aids for 10 years and never have had any brand only last 3 days. I returned and got refund

Don't waste your money!! Three out of the first package of 8 were already dead. I am lucky to get three days life on a battery where I used yo get 5-7 days with the Duracells Sam's Club used to offer.

Purchased these as they are a MM product and had great hopes. They last less than 2 or 3 days and go dead. A pack of 40 will barely last 5 or 6 weeks. Waste of money. Stick with name brand. So disappointed.

I hate the packaging on these batteries. You open the cardboard and they come out. The problem is, it is hard to only open it enough for 2 batteries. Unless the packaging changes, I won’t buy again.
