    "Not bad...5 stars...With so many remotes and electric devices around, it's always a good idea to have a stash of extra batteries, and these work great, giving a good charge, but not charging your pocketbook much at all....It's a pretty good deal normally, but I bought mine on sale for around $7, which is excellent if you're from the (admittedly dwindling) group of people who still need AA batteries on the regular"

    "I love...Good py...I bought these for my lights that run on batteries They far exceeded my expectations, after putting a pair into my lights, I left them on 24/7 and they did not die until after a full 7 days....Like I said when on sale I buy a lot of different sizes because batteries are expensive and the price you put these on sale for and how many you can get in a box is worth it."
