If you like RDAs a squonk is handy for driving. Dripping takes both hands.
I don’t know what BST stands for.
If you like big vapes the
steam crave aromamizer plus RTDA may amuse you. It’s a
tank, but it’s so huge you can drip it. You have to make sure the kidney shaped holes are completely full of wick though and when you refill close both the vent hole and the shutoff or it gets messy. For the wick I actually make a point on both ends, pull the deck and snip the wick on the other side. Easier that way. You know everything goes all the way down. Thats a cool feature btw. You can buy more than one deck, pre-build them, and use them like coil cartridges.
