If I had it to do over again I would have paid attention to those advising me to get an Eroll. I took advice on Joye Ego Cs and clearos as well as on a Vamo which sits in a backup drawer but I ignored Eroll advise because I saw so many people bash "cigalikes" and thought it fell into that category. I was soooo wrong. There's NO comparison to other products with a similar form factor. I finally broke down and got one when I couldn't make it over the 5 or 6 smokes a day hurdle. Now the Eroll takes the place of those.
The one thing I would have done differently is not stocking up on things (especially juices) before I really found the "right" thing. It's so exciting when you finally kick the smoking habit, and your tastes and preferences change so quickly at the beginning, that you typically end up with a cabinet full of stuff gathering dust. But that cabinet full of stuff still helped me find my go to devices and flavors.
