So... recently I purchased a Blu (yes I know Blue hate everywhere), and have been quite enjoying it, but I had decided if I'm going to put down analogs I wanted a better/different flavor and maybe a touch more vapor. Some people on here and elsewhere had recommended 306 cartomizers, so I ordered some. I also, ordered 3 different juices from backwoods brew: Maxboro,Smoke,Applewood. I've had the juices for a few days but just got the cartos today. Upon receiving them I filled them and let them sit for about an hour (one for each juice and a fourth with a mixture of all three juices because i felt like experimenting). A few minutes ago I screwed each one onto a battery and vaped with it a bit. I couldnt help but notice what I would describe as something somewhat like a chemical taste in every single one, it def was the prime component of the flavor. Now I'm wondering if it is something to do with the cartos, or if there is an ingriedient in the BWB juices I'm just not used to (as the Blue classic tobacco tastes like some combo of tobacco,coffee,and chocolate). I find teh amount of vapor produced pleasing and teh flavors seem good but there is a similar taste in all of them and I'm wondering if anybody knows exactly what it is? (the cartos came from eliquid planet if that helps any).
