on my cigalike batteries i've almost always used 100% vg and 2 days ago now i grabbed a 5 ml bottle of unknown composition out of my drawer. It's leading me to believe its got a higher in pg due to the reduced vapor. I'll also mention that its a bit lighter in color as well. I've noticed that my batteries are lasting significantly longer and the carto seems much better too. so my questions are basically these. First with the wicking issues i've heard of on the other delivery devices, are there any that can actually handle vg with ease? Second, why does anybody bother unless they have a pg allergy?
