So I got an acrylic drip tip and stuck it on my ProTank Mini and was surprised what a difference it makes. The drip tip that comes with the tank is stainless steel and therefore conducts heat / cold (this time of the year, just cold). Because the drip tip is cold, the vapor passing through it cools down tremendously. With the acrylic drip tip it doesn't do that, producing a warmer vape. What a great little $3 investment.
