I put this little button in my pocket to take it home, where I needed to change the battery in a meat thermometer. A few hours later, while sitting around a table with friends, we heard a loud POP! like a pistol shot, and I felt a sharp pain in my thigh. A puff of smoke came through my Levi's pocket. Everyone at the table heard it and looked around for the source of the noise. I reached in my pocket, and there was my brand new Energizer L44 Silver Oxide battery--in three pieces. No, I don't think I'd buy one of these again.
