We'll time to out provape through round two... The hardware passes the muster as far as living up to the hype. Customer service next as I think I have a faulty mini 18500 extension tube. Pinged them in sat so don't anticipate hearing back until the 2nd. Short summary is it only kinda works? I have a hybrid (I presume 2 tone anodized) unit that works great in 350 mode but is flaky in 490/500 mode (tried with two of each. Only thing I can think of is there is black in the threads if the extension. If I unscrew it a bit it will sometimes work but misreads the battery voltage.... I'm thinking it must be an increased resistance due to the threads being "coated". I'll let you know what they say. From all I have read I expect it will all go well. I just find it odd, as a fully charged batt reads on my meter at 4.2 but if I get it to work with the extension cap it'll read 3.7... Go figure. Anyone else have a "painted" one they can comment on?
