A month on and I've moved on to an MVP 2.0, iStick and a couple of CLK!s
Starting to try out RDAs (mainly for testing new juices before throwing them in on of my tanks!!!!)
I mainly use my RDA on the MVP, but they do work on the X6 as long as it's a single coil (been using 28 kanthal at around 7 wraps) the MVP and iStick fire much better, but on the highest setting the X6 works well too!!
Just don't try building on them, tried this and accidentally shorted out one of my X6s!!! Forgot the battery was on and accidentally fired it with a precision driver holding my coil in place while I tightened the posts (>_<)
