I have the ijoy limitless RDTA plus, and love that thing, no leaking no breaks and super easy to build on, even for beginners like me, superb flavor. I can't comment on the mod, since I am using the sigelei 200 touch screen with it, but since you wrote any ijoy product, I had to comment. Smok, on the other hand, well ppl that read some of my comments know how much I hate it. Mods are a piece of shit and let me not even start with the tanks and coils, as well as their rba's. Do yourself a favor and get a other rba, because trying to get some flavor out of yours, is nearly a impossible task, any other brand you can get flavor right away, even with the premade coils not just a hint of flavor. But that's just my 2cents on that topic.
