I've been vaping the Kanger Subtank Mini for about a month now and I am very impressed. Well made, easy to clean, variable air flow, great vape production, and OPTIONS! 0.5 ohm coil, 1.2 ohm coil, RTA. It's a solid tank. Massive O-rings so no more leaks like the original Subtank. I'm currently vaping Coval Vapes Pear Berry (awesome) with the 1.2 (actually 1.1) ohm coil at 20 watts on the iTaste MPV 20 Watt. Not one dry hit and great flavor. Must be the organic cotton wick. Blows my Aspire Nautilus out of the water. I'm very pleased. Nicely done Kanger!
