I am not a dripper nor do I really get all the sub ohming. I usually use carto tanks on a provari. My ohms are usually between 1.5 & 2.2. I usually have my provari set at about 3.5 to 3.7. I am a major chain vapor and vape all day long. If I go beyond 3.7 things tend to burn. I have one cart that is 3.5 and that one is set at 4.6. So here is my confusion. I am wanting a box mod but seems like the voltage only goes down to 4. Should I even bother? I really want the vaproshark for the size factor. I need something small and that totally fits the bill. What do yall think?
