Smok-tech XL LR 1.7 ohm 510 carto, for 3.7 volts only, Awesome TH, and Vapor production is off the chart. If you like the Boge 2.0, then you'll love these with nearly double the juice capacity, syringe filling IMHO is the only way to insure the carto is filled to capacity, eliminate all guess work in filling, 0 mess.
