Yes, the newer ones don’t have the metal ring and instead have a countersunk hole.Interesting. Can you see a visual difference? I have a newer model Flip and it works so easily that it's hard to believe it's even the same vape that one users had such a hard time with initially (though that update was substantial enough that it almost is a different vape). They must really work on/test these usability upgrades. Also, very cool about the chocolate!
