I was just given the Mutation V4 and want to be able to build super low on it. Right now I am using the Kbox mini. It is a 50w max and won't register anything under .4 ohm. I was looking to upgrade to the eleaf 100 but it has an ohm restriction of .15. Does anyone have a suggestion for a comparably priced device but has no ohm restrictions? Would I be better off going with a mech mod for the price?
