Good question! I'm 61 and RY4 and Coffee flavor trips my trigger! Been at it awhile, I used to make my own juice but it sat around and got stale, don't put much stock in that seeping crap, If you like it,(the flavor), you'll know right away!! I like bguying it in town now NO wait time, Any vendor is good its all pretty much pg and vg, Banana is good Creams are good and I like to vape Cherry Limeade to clear my pallet sic, between flavors......Vape On People
..........by the way I made that mod in the picture for my lovely daughter Jen in 2010.
