I work in an unsupportive (to vaping) environment and I want to stealth vape. But I find if I leave the riva in my pocket or on a lanyard for a few hours and then try a puff, it's dry even if refilled just before I put it away. So I have to take it apart, take out the fluval stuffing, fill and restart, and there goes my few minutes of peace and quiet. Should I just give up? go back to the old 510 and drip? any ideas? Will I have the same problem w/ a cart? I don't like them as well, though.
