I started vaping on New Year. First started with a JOYE 510, then upgraded to a Riva 510. I recently pic up a (2x AA Battery) 3.7 mod from the classified for a good price. When I first started vaping, I saw videos on people using a box mod, and it sure look awkward to me. I was like it look like you were sipping on a small juice box. I just wanted to say it feels awesome. It actually feels very comfy, and I like the feel on it better then my Riva. I'm very happy with my new toy
