I'm really enjoying my 3.7 ego clone, truth be told I'm too new to have experienced any other voltages, I dont even know what my starter PV was putting out. Although it is safe to say it wasn't higher than 3.7 lol. I do try to share any knowledge that I've gleaned from my tireless researching, but I'm definitely not a guru, not even close. BTW a Provari as a gift? nice friends ya got there, I haven't seen a mod more expensive than that lol.
