Cozz, I just saw your review from the Cignot store location and was waiting for you to show us the voltage with a 1.5 ohm tank. Have you done any evaluation of what happens as you increase the voltage while, say a DCT 1.5 tank is operating on the Twist? Seems it would hit 3 amps at 4.5v according to our friend Ohm. We have folks on ECF talking about how they didn't get that pleasurable vape they were looking for from a DCT 1.5 tank on a Twist. That's not a reason to diss the Twist. I just think most people don't understand the relationship between current limits, voltage, and resistance.
For right now, I'm just recommending that those people put on a 2.0, 2.5 or 3.0 ohm tank carto and try again to work around the 2.5A limit. Consumer education is key to product satisfaction. I don't have a Twist, but it looks like a good pocket sized walking around vape.
I love my Provari, too. It's a pocket full when you are walking around in weather that precludes a coat, though.
