Just want to say that I am really spoiled by the twists, spinners and other VV mods. Everytime I use a standard ego bat now it's only for a couple puffs. That extra .3 to 1.0 V I go up on the VV's makes all the difference in the world to me. It's the difference between vaping and vaping!
I have no need for the 5 or 6V settings but 3.8 to 4.4 fills all my wants.
