Those aren't v2. They're technically v1. I only refer to them as v1.5 becuase they're the actual cup I designed. V1 that some people refer to is actually the incorrect batch I recieved initially. I told everyone all about this in a post but a lot of people probably didn't see it. I could have simply thrown them away or shipped them out for people to use for whatever. Many of you will throw them away, some people may use them in other ways. It was better than me throwing them away though. I gave you the option to try it or throw it out. V2 is most likely going to be a coil embedded into the quartz, I'm still waiting for the prototypes. Once I find one that I like and feel you will all be happy with, I'll ship that to everyone that ordered these free of charge.
