My husband doesn't smoke too much, maybe 4-5 cigarettes a day ...
Then he smokes too much.
He obviously needs to stop doing that.
I'm a little surprised that you don't seem to have come to one of the main conclusions that I have come to after discovering
vaping; namely, that anyone who has the brainpower to conclude that cigarette smoking shouldn't be engaged in is an excellent candidate for cessation thereof through the wonders of vaping, because it is A) more enjoyable than smoking cigarettes, B) it costs far less, and C), oh yeah, it doesn't kill you.
Despite his recent journey to Florida to attend Wrestlemania, I'm going to presume that he possesses such brainpower. That makes me wonder why you think it will be satisfactory for the two of you to share a single PV, when he will almost undoubtedly start vaping.
Yes, I am frustrated. The e-Power is a slam dunk no-brainer for a beginning power unit, and you had one in your hands and didn't even try it out to see how it performed. It would have been great for your husband, or as I say, a friend from whom you could have spared the enormous hassle of figuring this all out.
As I type this, I'm vaping on my one remaining Joyetech battery, the passthrough, having loaned out the other two to friends of mine who are now off of cigarettes. I have no drip tip, having loaned out my last one to my friend Sean, who was struggling to stop smoking and is now happily vaping some Geoff's Blend from Tasty Vapor and a nice menthol-enhanced Mom and Pop's Tobacco Haze. I have a list with at least a dozen names on it of people I have or will lend, give, or obtain setups for because they are killing themselves with cigarettes.
I say this because I hope that everyone who reads this will make an effort to have at least one complete setup on hand at all times to be able to give to someone they care about and say "here you go". If they don't like vaping, which would be odd, then fine. If they do, they can reimburse you for the gear, and you can order another spare kit for the next person whose life you vastly improve.
Yes, I have been very direct. Life is far too short not to be, and even shorter for those caught up in the ravages of cigarette smoking. Knowing what we know, I think it's our duty as human beings to help others discover and fully appreciate this amazing alternative to smoking.
