Nope, dual coil cartos are on the Provari. Reo is for bottomfeeder. Using 306s and 510s on the Mini, Grand is HV 306s.
Don't see the need for a carto on a bottomfeeder. Cartos are for those
mods that you need some
juice capacity on which just happens to be like 95% of the market, haha.
Reo was so good, that I sold my 2nd GGTS +UFS if that puts anything into perspective 8) Broke a lot of hearts with that sale, never been hit with so many PMs in my life, but I made 1 person EXTREMELY happy. My Reo is not nickleplated, its not flashy, it doesn't have adjustable draw controll: but it works fine for me at work. As a power-
vaping mechanic, I stress test everything out there: Reo just works. All the other mods I enjoy on the weekends, when I'm clean and relaxin.
