I see a lot of folks fumbling around in the dark with RBA's, not knowing what they want from one. This is an expensive mistake in my opinion. Seems to me that a guy would be better off knowing what they want first, and then looking for the RBA that does THAT best. Otherwise most will find themselves telling folks that they love xxxx RBA when in fact they are just settling for what it does.
I wanted a RDA that best replicated the vape that I already liked best, and wasn't looking for a different vaping experience. I just wanted to be prepared should the FDA drop a heavy foot. The A7 (Pegasus) & A7 Mini fit that bill for me, but they can't do sub ohm if that is what you really want. What they do well is vape just like a normal 510 atomizer.
