Well I got my mother, a lifelong smoker, to make the jump to vaping. She started with a few 510 batteries and vision nano clearos. She really liked my ego batteries with the kanger t3 setup. Much better than the 510/ nano. The nanos are ok, but she doesn't like the draw on them. So I gave her a ego battery to use. She would like something around the size of a T3, but I know she won't want to fiddle with them to keep them working. Is there a no fuss no muss tank, carto, or whatever that she could use. Thanks in advance for any suggestions. Cheers.
