Pining for the Mountains
I wonder why they are so inexpensive?? Shame it won't fit a high quality banger like 710Coils with the thick sidewalls.
Pretty sweet that the cool down time is only just over a minute vs 3:30mins for constant gems rubies, however perhaps this is due to a lesser/thinner quality of ruby?
Thickness/total mass would definitely play a factor, but I think the biggest source of the discrepency is they don't tell you what temp you're cooling down to. It looks like GG is advocating for a hotter hit than Constant is.
