I must give my 2 cents worth now. I love love love my ego because I don't have to recharge
batteries every few hours. That is important to me. I use a variety of atomizers, LR and regular, cartomizers have their place too. I think I will try a 306 attie w/drip tip next. I juggle 2-650mah Ego batteries and a 900mah Ego battery and I have had what I needed, so far. I am getting curious about 5 or 6 volts though.
