Read your original post...if I worked somewhere and didn't want to drip, I would definitely want a bottom feeder. Have you seen the Reo's? I'm sold on them...went from a 510 e-cig and used atty's and carts too...and also a Riva but the Reo is sturdy and allows vaping all day long...the 18650 batteries would fit in the Reo Grand version of the Reo mod which holds up to 6ml of fluid. Not cheap but possibly the last mod you would buy. I use cartos and attys both on the ones I have and either work great. Personally I like EM 510 attys- (2 ohms on sweeteer juice and 1.5 ohms on tobacco flavored juices). With the Reo I can vape 100% VG juice without any issue of clogging although about once a week I do run warm water through my atty's and blow them out and let them dry- then they're good to go again. There is a huge subforum for the Reo Here: Reos Mods
