Works decent. Keeps smoke cool and helps with gurgle. Pricy, but you only need a few. The tobacco it saves you from 'wasting' would be cheaper to ditch than the crystals, though.

These crystals are way to expensive but the smoke is so much cooler with them that without. I will keep buying them so lone as they don't go up in price any more.
Work great - too expensive!

Make for an easy draw and seem to minimize condensation. I probably won't order again because of price.
