I justified the outlay on mine by looking at how much I'd save not smoking. At £7 a packet it won't take long at all to pay for itself!
Exactly, if you smoked one pack of cigarettes per day it would take less than one month to pay for itself.
The Provari will be my next purchase, work is a bit tight at the moment so I will have to wait. I settled with the Vamo at the moment, I will see how long that lasts.
When I first looked at the Provari I was put off when I read it had a microprocessor, in my experience, the more electronics, the more chance it has of going wrong, saying that, I have not heard any bad stories about it, and I noticed that it comes with a one year guarantee so it would more than pay for itself. I shall keep an eye out for how people are getting on with it!
