how do you get it to go up if both lowers it???Good battery life, a little bigger than other mods with similar specs. I like the interchangeable batteries and colors for customization. Good screen size and usability. Spring loaded pin allows any tank or rda, ohm reading to hundredth which is nice. The buttons seem to be backwards, the up lowers the wattage and the down lowers it which is a little weird but overall I really like it.
