I love my cartos, and tanks. I don't see them going away either. I have 15 mods here that I use daily, I am retired, so have plenty of time to vape, 5 of those mods are Reos that I use BF RDA's on, but the remaining mods all have cartos, and tanks on them. I am in the process of switching all my tanks to IBT tanks, best tank for the money IMO, and I don't really need a glass tank, I just really like em.
