Does anyone know the exact size of the glass fitting that the elbow fits into on top of the EV2? I want to buy one of these for my Extreme Q, but it has to fit into my 18mm female slot. normally I would assume it didn't fit because its a different vape, but the elbow peice accessory says it fits with the extreme Q, and if the elbow joint fits, doesn't this piece have to fit? seeing as the plug into the same spot.
