I have a BBB, and honestly I prefer the Q2 coils, which give great flavor, decent cloud, not so bad juice consumption as the 0.15 ohm coils burn through and at 40W on the 0.4 ohm Q2 I get weeks out of a coil. I rotate so I can't say it's my adv, but my current coil is about 4 weeks and still going strong.
The issue with any factory coil that's used on a fixed wattage mod is you can't break them in properly by starting at low watts and raising it as it continues to wick. I think that's where most of these coils end up with short lifespans. It's not just priming, but also working your way up to your sweet spot. Just priming and even giving it some time and even some unpowered puffs is just not enough to get the compressed cotton in factory coils properly wicking. As always, YMMV.
