Packaging needs work. It's very hard to get the batteries out of the package, even using scissors. Batteries work fine but need to be replaced within a week.

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.

These batteries are so much easier to get out of the packaging. The other ones were so difficult I had to use metal tools to retrieve the batteries. I scratched a few making them useless.

The MM batteries do work, but they are quite difficult to extract from the packaging without dropping them. The packaging needs to be cut to get access then the small tape for handling each battery is so tiny that it is useless for handling the batteries to get them into hearing aid. It is a bargain, but I probably won't get them again.

These batteries last as long as Duracell and Energizer batteries. I wear binaural hearing aids and these last about a week. I stream books and music a few times a week for hours so lasting a week is a lot of battery hours. Not only do these batteries work as well as the leading brands they also cost considerably less. A win-win.

I am usually very pleased with MM products, so I purchased these batteries instead of the name brand batteries I usually purchased. The name brand batteries last 6 - 7 days, these batteries only lasted 4. The sound quality was very poor. I will not be purchasing these batteries again.

No doubt these batteries are a good deal. However, Sam's changed the packaging making it very difficult to get the batteries out. I had to use scissors and even then it was a pain! Before I could get the battery out by hand. Sorry Sam's but this 73 yo will be going elsewhere. My arthritic fingers can't handle the change.

These have been very good batteries; however, grandpa really struggles with their packaging. He cannot open the blister pack without assistance. The paper won't separate. We have to use scissors to cut the package near the battery to release them and the plastic is very hard to cut. Although the price is good, and although the batteries last a long time, the inconvenience of needing assistance to open the package is off putting. We might consider another brand/option next time.

I have used these batteries for several years and they have always worked great. The new packaging makes it virtually impossible to open to get the batteries out. I will not be buying them in the future unless Sam's Club goes back to the easier to open packaging. Other brands have much easier to open packaging.
