I probably should have mentioned that, but I haven't tried myself yet. RBA's have a learning curve to my understanding, but I think it's not too hard to master. I was going to buy another glass cartomizer tank, but I think I changed my mind and will get a AGA-T2 as well!
I was rather intimidated to try a Genesis. I'm not a tinkerer. I like things that work right out of the box. RBA's do not fit that description.
I paid attention enough to know which of the less expensive rba's were being recommended. With the upcoming FDA rulings
possibly having a harsh impact on the availability of popular juice carrying devices, I wanted to have other options, such as a rebuildable. Wire, steel mesh, and silica are common enough materials that they should pass under the radar of the FDA in a worse case scenario. So having rebuildables in your vaping collection is a win-win in my book. It doesn't hurt at all that it's a darn good vape to boot.
The AGA T was almost univerally being hailed as the best low cost Genesis tank. When I saw they were being sold with a pyrex tank, I knew the time had come for me to jump into the game.
There definitely is a learning curve, but it's not something that anyone can not learn by educating themselves and then gaining some experience. It took me until my second mesh wick and third coil until I finally got to the point to realize the superior vape that the RBA's are capable of. I'm still a noob when it comes to these, but I was impressed enough to buy my second AGA. I still laugh out loud at the clouds of vapor that I can make, and the flavor and vape is so smooth that I often don't realize how much I am actually taking in.
Be prepared for early disappointments. It's part of the learning curve. I would spend an hour here and there, and then put it away. I was not dependent on it to work right out of the box. The pieces of the puzzle finally came together, and the vape experience can be likened to what I remember the first couple drags from a cigarette were like.
