JMHO
I was a 2 pack plus smoker for 35 years....after 3 heart attacks, triple bypass and complete disability from my vocation of my calling....Dr. said quit or die. Tried it all...everything medical and homeopathic ...eastern and western...to no avail. I found a kiosk with smoking everywhere and cut analogs in half, researched and found 510 manual..(more drag length...more vapor) and quit analogs. That was 6 months ago on the 10th of this month. I still had urges for analogs but fought them. This is where the Chuck comes into the picture...I vape my big chuck at 3.7 volts most times and when the "monkey on my back" scratches at me...I change batts and increase the voltage and the monkey just withers away. I NEED to have the higher voltage to kill the urge to "use" as I am an addict....not just to nicotine, I have learned. I am addicted to the ACT of smoking...the hand to mouth action, the oral fixation, the mouth, throat and lung hit, vapor exhalation and the mere act of holding the analog in hand or on self. I am an addict and I am in a remission thanks to higher voltage devices and the Chuck is my answer. There are other High voltage devices which I own and am happy with, but the switch is "no fuss" and works each and every time. It is reliable and after a learning curve at 6 volts, it is a wonderful device.
To answer the OP....The Chuck is the Answer for analog addiction....JMHO.
Hope this helps
