Sorry just posting this for informational purposes and not to compete against your device which is better designed imo. I will most likely have one of each when it comes to everything and of course testing purposes
Anywho, do you mean they filled the cartridge with like Arctic silver? From my experience that stuff is expensive.
Anyway,
It's all good my dude, I don't really see it as competing with mine since my vape is already openly inspired from the Glass Symphony (+Flowerpot) Plus the GS was always designed as a DIY vape, even when he was selling them the parts list and build information was openly available for anyone to build.
Yeah he used a thermal paste similar to arctic silver, but I believe the one he used was copper based. Just like attaching a heatsink, JoJo used the thermal paste to remove the air gaps between the cartridge and the thermometer housing. IIRC he went through a bit of trial and error with that process. It always seemed like the most complicated part of the build, which is what largely inspired me to go the coil route for mine.
