No work on weekends, and imo, the Vapesnail has no real issues, but the fill bung can come off if not careful. Instead of using something to keep it pressed tightly in, you COULD just secure it with the proper adhesive. I find it to be a non issue if filled while inside the Billet, but it could have been done better, I agree. The Alien is basically the same, where the bung easily comes off when unplugged. Again, though, its held in by the walls of the Billet's boro slot.

Very exciting news for you about the Blue billet...I'm heading to the product page now...
