“I don't recommend the 2.5ohm version of this to go with the itaste vv battery. It was a cool, smooth vape as promised by the higher resistance but for me it took it to an insanely too cool and too thin a cloud level at the only voltages or wattages it would run at without tasting burnt. I tried a few of the coils with both my batteries in case it was the odd defective one but bad taste started almost as soon as you upped the power at all. I have no issues with the 2.1ohm so I think I'll stick with that in future.”
