I have been using Fluxos for about a year, through the last several versions. I recently got the Phoenix TC and BC, to try. I'm very impressed with the bottom coil, although the vape is a bit cooler. For me, it's a toss up, between the Phoenix BC and the Fluxo. Of the three, my least favorite is the Phoenix TC, for a couple reasons. For one, while they don't leak, they almost wick too well. They tend to flood the cup, so that I have to clear it with the first drag. Once it's clear, they do vape great. Secondly, I like to take my cartos apart to clean them, and dry burn. The tubes on both the Fluxos and Phoenix BC are easily removable. It's very tricky to remove the tubes on the Phoenix TC, because of the way the base is built. It's easy to accidentally separate the two pieces of the base.
