My experience so far (2 weeks w/tank) is A: they are very convenient,no topping off every 5 min. B: I've had no leaking C: plenty of vapor
That being said, they taste different,I've tried the regular & the LR. I'm not a fan of the LR stuff, makes my juice taste scorched, same goes with the tank.
With the regular, it doesn't seem to have as much flavor or TH. You would think just the opposite, but I get more flavor from my Boge cartomizers & 306 attys, all on an eGo battery.
I'm puffing them side by side right now & the tank seems to have a dry taste, where the 306 & the carto deliver more flavor & kinda a moist taste, almost juicy.
The 306 is still my hands down favorite atty for around the house, carto's if I'm out & about. I will keep use the tanks when I'm on the road, but I'm not a convert . . . yet
