Alright guys I need some input on something. My Dad will turn 70 years old in a couple of months and I want to set him up with a new mod. He had smoked for about 57 years and when I started vaping he got interested and got him a beginners setup, now he gets upset that my clouds are bigger then his. I am going to build him a box mod, but it needs to be very user friendly, low voltage cutoff, go down to .5 ohms so I can get him the Atlantis to put on it, and have built in charging. What are some suggestions. Remember he is not tech savvy.
