Just a heads up for anyone else making thier own juice. I use a base of distilled water and VG for all my juices and occasionally add VG base nicotine. Some flavors are not working and some are in my pipe, everything works in the cigar so far. I don't know if it's related, but anything with PG seems not to work and gets cloggy. The flavors that don't work so far are the classic (PG based) caramel crisp from juicy liquid and Loranns chocolate. The Juicy butterscotch (VG based) from juicy liquids works just fine, even we I add the juicy liquid VG nicotine juice. I have read that some juices don't work with the pipe and it's true, but I wasn't expecting it to be flavor based.
