For anyone who's interested, here's a little update in my dominator saga.

The AFC ring was way too spinny, so I fixed it in place with some duct tape, lube and a whole lot of determination. This post is already sounding dirty, but I donI t mean it that way.
After many failed attempts, I managed to get a simple 1.2ohm dual coil dealie going on, and I have to admit.. this bugger is hitting like a champ. I never, ever want to build it again, but the way it's working right now, it may be my new favorite dripper.
Anyway, I gave my protank II clone and an ego with charger to my ohana uncle to see if he can handle switching to vaping. He loves it, but alzheimer's makes it difficult for him to remember how to do new things. I've never seen an ego like this, but it seems like it would be a good solution. Charging and switching the battery out less often would mean less chance for something to go wrong. Has anyone tried this one?
