So, I was interested in getting a replacement device for my Ego style batteries. I have a Kayfun Mini that I just love to use when I'm out and about, and don't really feel like hauling around my Provari. I've been looking at 14500 and 16340 mods, and I keep coming back to the ProVape. Sure, I wish it was regulated, but I can't find anything decent out there that is. So, my question to you all is: does anyone out there have one of these and use it on a regular basis, and how do you like it? Does it perform well? Do you use protected batteries with voltage cutoff, or just go unprotected? Okay, I know, its a few more than one question, but I'm really curious.
