In short, I shopped around for the best price on batteries and these came up.
I have used them without problem, they are fresh and dont have a stale date on them.
Customer Review: Clam shell packaging but good batteries Summary: 5 Stars
Once I got through the packaging I tested a few and they showed full power. So far, they are lasting well in all the toys.
excellent product for a very decent price - prompt delivery and battery life more than expected
Customer Review: Good value Summary: 4 Stars
Considering you could pay 75 cents per battery in a store, this a good value. I know they're not Duracell, but the way all batteries get "eaten", this is more bang for the buck.
Customer Review: Cheap, but you get what you pay for Summary: 2 Stars
Compared to a higher quality battery (eg duracell) these batteries seem to last half as long. If you need cheap batteries that last like the ones for sale at the dollar store, this is your battery.
