I have the istick ipower 80w 3 of them going strong 2.5 years later.Thanks for the info. Yeah, I noticed KangerWholesale is out of Zenith coils. They had that good deal on them a few weeks ago, and I got 10 boxes at the time. Looks like they're getting more scarce.
By the way, I love Rocky Mountain Vapor. Great folks. Isn't the 30w istick the one that many folks felt was superior to the others? I seem to remember that from my very early days here about three and a half years ago.
