Honestly you won't like this but I wouldn't buy a 30w device unless you know 1000% that it's gonna be enough power I bought a DNA 30 and found out it wasn't what I wanted and picked up a 50w ipv2 I wasted 120 on the DNA 30 wish I wouldn't have done that that's just me if your ok with 30w and the price of the evic supreme I'd go with that lots cool features to play with
