I'm with Randy C. Been with V4L since I started. Got their Titan XLs about three months back, and a couple of tanks. LOVED 'em. Then, thanks to ECF, bought a couple of kGo 1100 mAhs to recycle. Loved THOSE. Now, the Provari V2 is on its way.
Of course, I've had to enroll in an electrical engineering course to understand what I'm doing.
But the assortment of carts, tanks, lo-res / standard-res, Stardusts, drip tips and great new flavors I've discovered after being happy with Tasty Vapor's Cafe Machiatto for two years -- somehow it's all WAY more involving, pro-active, interesting and CHEAPER than buying two $5 packs of analogs a day to kill myself in slo-mo.
One month's analogs alone costs more than the Provari, so the cost is negligible.
Can't wait to vary my voltage.
