I thought it was crazy too- didn't hink it would work it went against what I thought I knew- as I get older i learn how much more I need to learn.
Still doesn't make sense and I still use my radiant quartz heater in place when able because it is warmer but the candles have kept me warm a afew times now….and I have used them in smaller spaces where warmth is helpful- like near a cutting project.
I agree with you Ranger- it may just be that we are so damn cold that any warmth actually seems like more lol!
