Ok I noticed on my provari mini that my HH.357 wobbles side to side and I'm really down about this. I put few tanks on and they also did this and started to think it's my pv. But after really trying to decide if it's my pv or not I noticed something. Now when I put the cart tank on and tighten all the way (completely flush) it doesn't wobble. Guess I didn't tighten completely you would say. And being flush stopped the wobble. Now my adapter I got from sweet-vapes (bought it from there as its 5 min drive) it stops screwing and has I'd say a good millimeter or 1 1/2 millimeter gap and can't turn no more with hand. I would have to have to take a screw driver and tighten it down full which then would push the post on the adapter up which would be fine. (Not sure if the provari batt post moves or is completely solid with the top cap.. worried about twisting adapter with a screw driver and causing harm to the provari if the battery postt would move) **update as I'm typing** I got it fully flush on the provari and no harm done. Just can't get the atomizer flush with the adaptor. Where can I get a quality sealed adapter without wiggle and both ends are flush with a pv and atomizer?
