I purchased the H Priv 2 about a month ago. The first one worked about a week and the screen died. It would fire, but no screen, it wasn't in stealth mode. The company I purchased it from replaced it. So great, grabbed new, freshly charged batteries, popped them in, vaped on and off for about 3 days. One day, it just wouldn't turn on. Doubled check batteries in another mode, fine. Bought new batteries, charged them (I always charge externally) and still nothing. I'm so irritated! I contacted the company and demanded a refund. I will never buy another smok product!
