@Bea-FL, the $15 VTC Mini with Tron S is here:
They also have Tron S and Tron T tanks for $2 each. Both models use the CLR coils. I have a Tron S that I find just as good as the eGo tanks. I don't have the T model, but Puf does, and it seems on a level playing field with the eGo.
Money is tight at my house due to recent life events, so the only way I can justify blowing it on something I don't need is if I get a great bargain (yep, that bit of delusional thinking actually works if you're simple minded. Works on me.)
as far as I can tell, all the eGo ONE tanks that use the CLR coils vape the same or so close I can't tell any diff
the Tron tanks are still eGo ONE tanks, just a diff model...
