Kinda related:
I broke out the Engine II on the back of this thread. Four coil attempts, a desk covered in juice and multiple swear words - it's a good job I rate the Crius dripper because otherwise I'd have been marching to OBS to give them a piece of my mind...and that wouldn't leave much left.
Actually have a really good vape now, so there's that. Flavour is a step up from anything I've had on any other atty with Mary's Lemon Madiera. All my failed attempts were with funky coils; the 316 wasn't recognised, two types of premade Claptons gave an awful experience - now I've just got simple 7wrap 0.5mm Kanthal, ohming out at 0.4 with 80W.
Taken a couple of hours of my life mind you.
