Hello everyone. I've been using my tornado/ego for a month or two now with low resisance attys and am enjoying it, but I feel like I want a stronger vape. I'm excited to try 6v but I was wondering, is there any difference between 3.7v devices? Will the SBs 3.7 be any different from my tornadoes? I'm just trying to justify the size/ price to myself. Thanks everyone :]
