bells and Ken are both technically right about the "key" going inside of course...
But I've always called a 6-sided tool that goes on the outside of a bolt head or nut a "nut driver" if it's attached to a screwdriver-type handle, or a "socket" if it attaches to a ratchet or other handle.
This Sub
tank Mini just keeps on impressing me. Yesterday while trying jooses at the B&M, I got tired of trying to get anything out of those clogged clearos they had, so went to the "dripper table" to use those juices in bottles. There they had two Igo-L's with some sorry looking coils, and some cotton just sitting directly on the not-too-clean-looking table, so I didn't really want to use those.
So I just took the base off my Mini and dripped 5 drops directly into the hole in the top of the RBA head. After trying 3-4 fruit flavors, some fella told me I should try a flavor he liked called Leather, so I did... without smelling of it first. Big mistake. Now, I love the smell of fresh, quality leather... but this stuff tasted like old, wet leather... yuck. Ruined the taste of my RBA build.
This morning I washed the
tank, rinsed the RBA base with the wick still in it, blew the whole thing out with compressed air, put the chamber sleeve back on, massaged the wick into place, wet it with some fruit joose, filled and reassembled and... It's working like a champ! And the Blackberry Brandy I bought actually tastes pretty good! oooraaahh...
