Thanks for sharing. I'm about to find out for myself. I said that I had no interest in variable voltage until I finally had the chance to experience it.
Having been content with my cartotanks for several months, I've been intimidated by the "tinker" aspect of getting into an RBA. I prefer to use things that work straight out of the box without needing any fiddling. Having said that I've keeping an eye on these from a distance, and I just purchased the new AGA Tiamat PLUS with glass tank this past weekend.
AGA Tiamat PLUS - Rebuildable Atomizer.
I've noticed how the popular RBA's quickly go out-of-stock, so I like what I had read/saw with this one, and hopefully I won't have buyer's remorse.
