i’m over 60 and had a hard time taking large deep bong hits with my aging lungs. The Glycerin Coil works amazingly well at cooling the smoke and looks awesome on the Stax base. It helps lower the temp of the smoke allowing for a larger, cooler and safer hit. Usually on the 4th or 5th use it needs to be blown out to remove any condensation and ice build up inside the tubing. When not in use coil is stored in freezer which also might slowly contribute to ice buildup. Also, do not use ice in the Triple Pinch Mouth piece, The melted ice water will refreeze in the Stax coil below blocking air flow.

Absolutely awesome! So smooth!

I love my new glycerin coil! The hits are so smooth and cool. The price was right too. I am very happy with my purchase.
