Just a word of warning to all my Muddy Buddies out there: DO NOT GO ON HANK'S MUD BUTTE RUN. We did some investigating and it turns out this so called "mud butte" is just an open septic system that was used for the old farm down the road. A few of us came down with some pretty bad dysentery and poor Grayson came out of it with a case of the ol' stink eye, pink eye! In both eyes! Anyways, these batteries work alright I guess. I gave this review 4 stars instead of 5 because I bought the wrong size. I don't really have anything that uses D batteries, so if anyone wants to buy the rest of them let me know.
