I agree with that...... If I picked up an old 901 it would be like vaping air now. But in the start it worked fine. I have been vaping 2 1/2 years now... I figure next year I may need to go with a car battery....lol
I've noticed that it's taking more & more to give me the same TH too. Do we somehow become immune to it? There's no way I could take a full hit off of my cartomizer when I first started...
