I know people get excited for new stuff, but until there are reviews out from people who have had a new device for several months, I wouldn't invest in it. It's $70 here, a warranty purchase there, different batteries because the length is different, and soon you're in for $100. The button may fail in a month, the voltage regulation may be lousy, it may throttle at higher voltage with LR stuff without warning, etc., and without reliable reviews available, you're the guinea pig.
With all the well-tested and known-reliable VV mods available (BP, IPro, Darwin, Provari, etc.) in the $100-200 range, I honestly think you're better off investing in tried and tested technology and not being a first-adopter (which is always expensive in the long run).
