I love the MM ice balls. I placed one in s highball glass with ER 17 yerterday and left it on the counter while I finished putting up the christmas decorations. I heard a loud "POP" and looked back at the glass. The ball had shattered into about six pieces and splashed my bourbon all over the counter. Only lost some bourbon and glad it didn't happen while in hand, kicked back and relaxing in the easy chair. tim
