I dunno. The ring is loose and moves around, so I can have a gap anywhere and not just lower right. I can position the ring perfectly in the middle but once I pick it up to vape and place it back on the desk, the motion would move the ring slanted. I tried at least 4 different Boge-Ibtanked on 3 different provaris and have same problem. I also have a design-1 (the one without the dimples) from Kir Fanis and same problem. Doesn't bother me too much since I have a pro-ring from Lokilab that fits perfecly so I just use that with my tanks when I'm out and about. At home or office I mainly use RDA without the ring or with hippo anyway.
Mrjayd - That charger is XTAR VP1 I got from RTD VAPOR. It's funny, the "XTAR" face plate is crooked (check out the pic and you will know what I mean). Again, doesn't bother me too much since it functions/charges perfectly. I guess just shaky hand when gluing it. I see a trend here. Crooked pro-ring and crooked Xtar logo. Just my luck here. lol
