I know you enjoy your eroll but I am going to be honest with you.
I started with the ego-C system which uses the same atomizers as the eroll and has only a slightly larger tank (.75 mL I think it was). It was MISERABLE. Those attys clogged constantly. A full out dry hit on one gave me a 4 day sinus headache. They are expensive. Filling the tank constantly drove me INSANE. It WHY I have never tried the eroll. I would rather use a crappy cigalike with cartos for driving than deal with those attys and tanks ever again.
I really didn't start believing vaping would work until I got a real clearomizer like you did tonight.
Yeah, I started getting tired of all the refilling/recharging nonsense when I'd had it about a week, and i wasn't even vaping *regularly* at that point, but still smoking about 8-10 a day.
And just today, I got to discover what happens when you overfill the tanks a little and it leaks into the atty... that gurgling sounded like my lungs in the morning! And the TASTE... BLEAH!!! I really think I got e-juice in my mouth this morning from all that, and man it was NASTY... I was rinsing and spitting for a half hour after that, had to pull out two new attys because the ones in the eRolls were just wet with e-juice.
Oh, and I discovered a new trick, don't know if y'all know about this or not, I haven't seen anything about it online. You know those little silica gel packs that come in stuff like shoes, medicines, all kinds of stuff that should stay dry? It always says on it DO NOT EAT, like someone might be tempted otherwise.

That stuff is a dessicant, it dries out anything enclosed with it. I get those with each inhaler, and always before I just tossed 'em... but now, I use them in closed plastic bowls to dry out vaping stuff I've washed, to finish getting them dry -- right now I've got a whole set of attys dryng out in one of those bowls, with 3 of those silica gel packs. So when you get new shoes, or anything else with those little packs, don't toss those packs, save 'em to dry out your vaping gear!
