I've had my vmax long enough to compare it with others. Please don't get me wrong because I really do like my vmax. Heck I sleep with it every night. My problem is: if i set it to a certain voltage then make it that voltage. I don't like the variable stuff. I got some twist, some spinners, and just got a ITASE when I set them I can get a good vape. When I set the vmax it's burning up everything I got. Yes I've gone down to the lowest voltage and it's still to much for me. (Just me not the equipment) Set and calibrate your product like it should be. Stop the variable stuff. I was gonna buy a zmax but after hearing others on the forum I'll just stick to my little funky itaste and twist for now. (Cant afford a provari and it wont do anything the itaste wont do). And besides for a noob the itaste will even suggest a voltage for you. Let the argument begain!!!
