I just got my hand on this big 'ol cartomizer called the "3.5ml Giant Cartomizer with LED" from "vape in the cape" (though a few vendors have it.) In fact, they sent it to me to make up for the fact that they were out of the thing that I ordered. At first I thought "it light up?" how silly! But I filled it with my favorite juice (rich cream from vapor kings) and gave it a whirl on the eGo. OH MY GOD this thing is so amusing! It's a good vape too, but the light makes it seem... so... *powerful* don't knock it till you try it. Just ordered 3 more, Guess they knew what they were doing when they sent it to me. What other cartomizers light up? I want the full collection. Ha!
