“If you care for vapor production than this is the best cup for the switch. Id say its a good 30% more vapor production than all cups and 30% more taste than the quartz cup while being 1 temp lower than quartz ( 3 on blue ) which means a smoother hit. It's also the easiest to torch/clean residue will evaporate in seconds with this cup and then its brand new. ALN and Quartz you have to get them red hot to clean properly, Sapphire you cannot clean with a torch unless you're extremely careful. I think this cup has the most overall benefits.”
