I've been through a ton of various mod devices since 2007, beginning with mechs, of course. My Provari mods are hands-down thee best! A recently purchased
hcigar VT Inbox has been my go-to at home
device for the last several weeks, but if I go out, I default to my Provari P3 Ti (or 2) without hesitation. Provari sent me 2 x P3 Ti mods for the price of one! I don't know if this was a mistake or them trying to unload what stock they had left? My Provari 2 is a stainless steel built model that has been kicked, dropped, thrown, and dropped in a toilet... It continues to operating as new. If there is such thing as a must-have mod, it is surely the Provari.
