As a die-hard flavor-chaser, I've been rotating between three 22mm attys: Serpent Mini 22mm, Goblin Mini v3 and Oumier Whitebone Mini. All have performed admirably with the Oumier having the least condensation. I recently acquire this atty based on rave reviews and was regretting it from day one Problem #1: Draw too tight. Even at the largest setting, 1.8mm, I struggled to get a satisfying vape. Solution: Remove air flow control (AFC) ring. Looks ugly, but now all the holes are drawing air in. It is Ok, but it is still not enough to get an airy MTL draw. Problem #2: Dry hits. Wicking specifications are unforgiving. Solution: Precisely keep wicks barely touching end of well and ensure wick is properly thinned out as many have demonstrated. Problem #3: So-so flavor. An inner diameter (ID) of 2.5mm is typical and pales in comparison to any of the classic attys I've been rotating. Solution: Maximize micro coil. A 26ga, 3.0mm ID with 8 wraps, about 1.1 ohms, generated excellent results - both in flavor and vapor volume. Unfortunately, 3.0mm is the maximum clearance. Using 24ga will invite a short. Problem #4: Heat. The default drip tip with heatsink can easily come in contact with lips and mouth. Solution: Use the supplied delrin drip tip (black, one piece) or your own drip tip. Having sorted all the problems out, I now thoroughly enjoy this atty. A BIG PLUS is it is apparently leak-proof However, If I knew all these issues in advance, I wouldn't have bought this atty. Buyer Beware!
