2-V2-Provari's, 2Darwin, 6Reo's,,,,, other's +++++ There all great PV's, the first 3 I mentioned that is,,,, but the Reo's are truly special Mods, especially my VV Reo Woodvil Rob sent to me, this thing is a monster no flooding, perfect feeding, same hit after hit perfectly consistent every vape,,, Filler type Cartos I just cant use anymore I hate them all,,,, Atty's are so much better for me,,,I've got 5 Reos with 357's on them all 5 357's are running for almost 6 months now and I use them all every day. ,,, these Atty's not only last but run super on the Reo's. Keeping them wet is simple with this Mod and the longevity of the 357's lifespan depends on keeping them wet for sure,,,,,,, Do yourself a favor get the VV Reo Woodvil or Grand when it comes out you wont be let down by any means. Dialing that Atty in is key to max flavor/Vapor and this Mod works super for this, and vapes like a freight train. The VVPV is another awesome super Mod too
