I have personal experience with the bricks. 50 yrs ago, or so, it was my job to take care of the cigar case in my grandmother's candy store. I soaked them every week or so. They don't work worth a fuck and anyone who says they do, doesn't know what he's talking about. The difference between the brick and the bead is like the difference between flint and steel and a S.T. Dupont lighter.
