Mig Cig has their stuff made by Kanger - or at least that's what they claim. When I last looked at it it looks nothing much different than a Kanger E-Smart - but a lot more expensive.
The other problem with their stuff is "mystery threading". I think it's some version of 808 - but I won't commit to that either. And Mig Cig sure isn't going to tell you - so you have to keep buying there... ah... "stuff."
If she wants something small but similar, if you
shop around you could get an entire 2 battery, 2 clearo & charger Kanger E-Smart kit for about thirty bucks. At least that uses standard 510 threading so you aren't locked in to getting clearos from a place like Mig Cig. E-Smart or any basic CE4 mini clearo with 510 threading can be had for about two bucks each. Charging $14.95 for a 1.3 ml clearo is outrageous.
Bottom line: If a supplier won't tell you what threading their connectors use it's time to walk away.
