A Smok mod is something I'd get from a trusted vape shop that knows me, with the understanding that they are comfortable replacing it or giving store credit if there are issues.
I got an Alien that way. They got too many and had them on clearance. They replaced mine twice, but third one had been good for about 5 months.
Have 2 stick v8's. The larger one with big baby has stopped firing. Have an older Koopor Plus, just too many issues not reading resistance right or not firing cleanly after awhile, so I retired it.
Instead of the X-Priv, maybe Revenger, or any of the Smoant or VooPoo devices. Or even the Ravage 230 and similar Espion. Asmodus is usually good, costs a little more, but they are not cookie cutter.
