An atomizer (not a rebuildable, just a LR standard) with a lifetime warranty, no questions asked. Strangely, when I started
vaping in 2008 (cigarette style of course from a brand that has fallen WAY out of favor with the public), I bought a kit with two batteries, an atomizer which was a "gold edition", a 5-pack of pre-filled cartridges (menthol), and a slick looking case that held two carts, the extra battery, and the e cig (assembled). This atomizer lasted me almost two years! Now, I did stop using it after about 3-4 months of heavy vaping, but a year later I found it and bought some new carts (empty), filled em with e juice ($30 for 10mL), bought a new charger, and it vaped just fine until I lost it in a move. It wasnt until a year or so ago that I found out that atomizers are only supposed to last a short while. Stranger things have happened, I guess!
