Rick, I may be kinda hard to sort out? :~)
My sweety likes the m402 cause it's lighter. I got her 2 batts so it's not a prob for here to stay charged up. I just ordered her some 36 juice. I am hoping that will help. I will try it also. We are both doing 24 now. Oh, I just have one batt right now but just use a 402 batt while mine is charging.
I am wondering just how much better the vape on a 510 is, compared to my 401? I think my vape is fine on the 401 but I have not tried the 510. It is just not satisfying my nic urges. Maybe the 36 juice will help?
But oh, making a good pot of chili IS considered gourmet cooking in my neck of the woods. I am mostly a soup, stew, roast cook at this point.
