I've only been doing this for three months. A world of confusion, I fear.
The T2 has a top coil, with long wicks to absorb the liquid. (like a Vivi Nova or iClear).
The T3 has a bottom coil, with short wicks to absorb the liquid. (like an EVOD or Pro tank).
I have tried both and prefer the T3 for flavor and not having to tilt to keep the wicks wet. Both types work well and it's just a matter of choice. (my wife prefers the top coil Vivi Nova)
Don't let all the batteries and liquid dispensing devices confuse too much. A simple battery on a T2 will work about as well as anything. Hobbyists sometimes go overboard with exotic devices.![]()
I do simple cleans by filling the tank with everclear (you can use rubbing alcohol) and soaking overnight. Then rinse with water.
