I found Pax to be the same.
Smokers seem to do better on butane vapes.
Try a dynavap or a stickybrick. Both have a learning curve but smokers love dynavaps and the stickybrick is as hard hitting as vape gets.
If you buy from Vapefiend with the code 420 either will ebay for almost the same as you paid if they don't work out.
Just my thoughts.
