So I still love my njoy and am very successfully refilling the cartos with the "condom method". I've been on the fence about an upgrade. On one hand I like the cigalike aspect of the eRoll, on the other I already have one (the njoy). My question is has anyone gone from an njoy, BLU or something similar to the eRoll and if so was it significantly different? I'm also quite curious to know if anyone has BOTH the eRoll and eGo C that can compare? I'm looking at Rocky Mountain Vapor kits...they have the ego c with a mini ViVi Nova kit OR a Vision Cleromizer...they're only $2 different, can anybody tell me which they'd prefer and why? For $2 I don't care about the cost...too many damn choices! For what it's worth Dave at RM has been very helpful answering my questions thus far, not that I feel he's pushing a sale or anything, but he commented the Mini ViVi set up is his most popular kit...just curious what this community has to say. I don't want to sit on the fence for ever! Thanks in advance for your input.
