Yes Least, some mechanical inclination is needed but aside from charging, filling and changing coils it's non-stop puffing. Cigs don't really compare. Some find the nicotine pull much less than with smokes. I can go 2 hours w/out vaping--never went 30 min. w/out smokes. I can tell you I feel good enough to get on the treadmill after smoking 38 yrs. I can't believe how much better my breathing is.
