Just received my Vamo V5, and have already burnt two coils. Before using it, I watched a few youtube videos on the V5, and see people setting these at around 4.3v with the coil reading 2.7 ohms in a protank. The third coil is working just fine at around 3.3v, but if I go over that, I start to feel the burnt taste coming on. Is it just me, or is this normal? I was hoping to be able to get a little warmer vapor out of a protank on this Vamo V5.
