I don't think pure 100% Pg is good, probably too harsh I suppose. Mixed with the Vg it is smoother ,sweeter and less harsh.I got stuck with 100% Vg and it seems to clog everything and shortens life span of atty's ect.Like
vaping maple syrup almost.I need more Pg than Vg in my juice.But I'm sure there are vendors who make good 100% Vg juice.Probably why I've been having issues with all my gear,No more 100% Vg for me pal,Time for a change.
