Very difficult to open the package. The first battery I installed lasted only 2 days. The next 2 I tried were dead on arrival! I will be returning them.

I will pay more somewhere else rather than buy this terribly designed product again. Someone should consider their consumer rather than put a product mostly used by elderly people in a package that requires tools to access.

Affordable batteries for hearing aids. Once in a blue moon, a battery is no good but not often. Good quality and outlasts the more expensive ones. Always buy!

Members Mark is one of the first hearing aid batteries to come with new packaging that protects children from accessing and mistakenly swalllowing the small batteries for candy. The packaging is a bit challenging for me to open... but worth the effort as it protects children from small but deadly batteries. I am getting 7 days on average for the hearing aid batteries.

The quality/life of the batteries are terrible…. Out of 1 wheel, you might get 2 that will last longer than 2-3 hours before your hearing aids give you the low battery warning….. then the ones that do last longer than a day, maybe 3 days…. If I'm lucky…. I've bought 3 packs so far thinking maybe I just had a bad batch. Nope… same problem will every batch… and before you ask, batteries are stored indoors and not exposed to extreme temperatures… don't waste your money. Spend the extra 10 bucks to get an actual named brand battery that will last you a whole week like they should..

Batteries do not perform as they should. Only last a day or two.

These batteries are great, they last a week.

These batteries are now sold in the circle packaging (as pictured), instead of the former cardboard sheet, punch-out. The new packaging is very thick plastic that requires heavy-duty scissors and my husband's strength to cut them open. This "child proof" packaging is also ADULT PROOF. It's nearly impossible to access the batteries. It's very hard to cut, and once open, the battery typically goes flying to parts unknown. This is NOT child or pet proof packaging!! It can be difficult to find the small battery once it flies out of the package, due to the pressure needed to open the package. Eveready carries this size battery in the cardboard packaging format that these batteries USED to come in. I have switched to those, even though they cost me more, because I can at least open them, myself!

The price is great, but the packaging is impossible for elderly or those affected by arthritis. I was disappointed in the life of the battery however I'm not sure if cutting them all out of the packaging shortened the battery life as i had to do this to make them accessible.

Extremely difficult to get out of the packaging.
