Just got back int buying supplies online and the first thing was the Ego ce4 kit eGo 650mah CE4 Kit. A while back(like 8 months ago i bought enough stuff to last till now). I went with the kit cause with the prom it was under $33. Man do those ce4 tanks rock. I used to use the plain old LR 510. I am now a convert. Sometimes you get lucky buying something cause it was a deal. I can' believe how much the e-gig has advanced in just a few months. Thank High Desert.
