What's your favourite, most convenient method of testing multiple liquids and which equipment/atomizer will you use? Don't want to fill a Protank with 2-3mls of juice and then go through the hassle of cleaning the tank up, changing a new wick. Please share and discuss.
Seems to me that the HH357 is one of the more popular choice.
