Disappointed with useless product
I tried these as instructed. Expanded in water just fine. Added 10 to my water pipe, the max recommended, to the dry pipe. Extremely harsh, even with a light pull. Then I froze some and it was no better. Plus some had disintegrated and some were mush. Some have said that using double or triple the amount works better. It still doesn't compare with water. Also the residue was still on the glass, not the beads. Save your money for super coarse salt and alcohol.
