I have been lurking around here for some time now but haven't really posted anything so I thought I'd kick it off and start getting my post count up. I have had a 510 for some time now and finally ordered a ProVari the other day which shipped out today. I can't wait! The biggest gripe I've had with vaping is trying to find consistency with atty's (I prefer LRs) and being tethered to my USB port because of the short battery life with my standard 510 batts. I'm hoping that the ProVari will be the end all to most of my problems! And BWB Ry4 is my peronal go to vape!
