Even though a lot of people like to put down B&Ms for being expensive, this is one area where I've been served well.
Got my first carto tanks at B&Ms. The guy at the shop primed and filled my first one, and it's been a piece of cake since.
Thanks to Nick at Vulcan Vape, I've had nothing but success and great flavor from the carto tanks. Not only that, but from reading here about wasted cartos, it seems like I've saved money.
