I have an eleaf Istick 30 watt and i am pretty much settled at having the Mutation X V4 being my first rda. My question is more about looks really. I have this problem buying any new tank or anything online. My Istick is blue. What color of Mutation is going to look the cleanest. Stainless, White or Black? Also any other advice about the Mutation you might be able to throw into the conversation is appreciated as well.
