i have been vaping for 19 months and i learned that i have a problem with cartomizers that have polyfil, they give me a sore throat. i can use the same juice in an atty or in my CE2s with not problems. this is what made me make this mod. I decided to try these ego DCCs due to all the good reviews i heard about them. so i ordered a few of them, fill them up, fire them up and the next morning wake up with a very sore throat. so using these things were a no go for me. but i really liked how sleek they made my ego look. then i got the idea to just turn it into a giant clearomizer. the whole process was very easy (only had to reattach two wires) and took maybe 20 min,if that, and no leaks as of yet. the pictures speak for themselves. and this is putting out more vapor then i ever got from the DCCs
