Started with greensmoke a month ago, trying to get off Backwoods cigars(inhaling). Greensmoke has good flavor but too costly. No way you're going to get 360 puffs off each cart as they claim. Got the Halo triton last week and love it, way better than cartos. So far using tribeca and torque, they taste great, going to sample longhorn and turkish soon. Mfr says to keep tank above 2ml at all times, hassle to refill everyday but still better than cartos. Glad not be smoking cigars, just turned 60 and I work in a hospital so I should know better. Still get urges for a real smoke but so far it's been manageable.
