I just purchased the new pack of batteries and compared to the old blue colored ones, these feel less heavy. Hopefully that doesn't mean they last less, as they've been pretty reliable in the past. Only time will tell.

They are not good,and they leak acid all over the place!

Runs out of power very quick. Waste of money. other products are good.

These Sam's brand batteries only last 25% of the time verses name brand. Don't buy!

Mediocre performance at best. Not recommended.

You can never have enough.

Great value -- same as Energizer!

Keep leaking and ruining my childrens toys. Rusting out the contacts

These batteries keep leaking and ruining the products they’re in.

Constantly replacing them compared to when I used name brand. Won’t be purchasing again.
