Adults only (21+)

Got it 2 days ago. The 1 feature that is annoying is that u need to unlock it to do anything (pre-heat, power settings, anything). If someone could explain auto lock and why? We'll see if I get an answer?

Yocan Ziva Pro

Ok so first off, the touch button - more like a tap hard button with your index finger tip... it works the screen which is very cool and includes lots of geek stuff.. ie; puff counter lol, volt setting I like 2.8v, ohms, battery level and I think the timer is your last puff timed... I think this is the best handheld little buddy ever. Super stealth, no cartridge or anything visible..

the first Ziva I received did not function properly, the button doesn't respond to anything aside from off/on. I contacted someone through the chat feature on your site. They were prompt and gave clear instructions on trouble shooting. They also quickly sent a replacement device out to me that day. Unfortunately the replacement unit has the same issue. I didn't bother to contact anyone as I figure it's probably an issue with the entire line.
