Does he has any evidence to proof that it'll trigger circuit break, explode

shock

your pv or ur genesis atty? Did you ask him why and how since he's an experienced PV's seller? Then which atty is suitable for Zmax? Or he just heard it from a rumor...
I don't have Zmax so I don't know much about it, but I do know and studied its specifications from many reviews. (Actually I almost buy Zmax but I found Vamo has much better user interface, easier to operate a lot.) Zmax has short circuit protection, reverse battery protection, over-discharge protection... lot of protection! Genesis style atty sure is not for beginner, you need some electricity knowledge and a ohm(resistance) meter prepared. When you built your coil and wick you need to test your atty with meter to confirm it's not shorted or its resistance is not lower than 1.2 ohms. But, even though you have too low resistance or shorted atty, still Zmax has its protection and will shut out itself or alert you a warning or error code. Zmax, Lavatube, Provari, Vamo or most popular APV mods are actually designed and built for people who use rebuildable atty... IMHO. Unless the device is defective...
Any experts here? Please pop up and say something?
