I have a couple of questions and need *simple* answers because I'm a real beginner. Have a Joye 510 and a Riva 510. Like them both. But can I use drip tips or a 510 T atomizer on the Riva? My least favorite part of this whole experience is filling those little cartridges. Necessary for when I'm away from home, but otherwise a pain. Please help. And thanks to those who do.
