Good morning, NHALERs!
I learned something new this morning...and I didn't think THAT was possible before 8 a.m..
I though all atty's that could be rebuilt were considered RBAs....whether it was in a tank or for straight drip.

Never heard of an "RDA" before. Thanks for your explanation, Slasher!
Now I have a question though....there were a couple examples given as to what is considered an RBA, but a ProTank 2, some CE4s, and ViVi Nova can also be rebuilt (coil n'wick)...so what is the difference between the examples and these? Is it simply the wick material? Or maybe the complexity of the system?
