OK I got my Igo_L and my wire. I was at a get together saturday night and a gentleman there showed me how he builds them. Very informative. I went home and rebuilt one and threw it on my RDA. It worked OK but the second time I put the RDA on my Itaste. the threads crapped out. I doubt I buy another. Desertvapes where I purchased it told me there is no warranty on their products so I'm just out the $13. While that is not a lot it's more than I like to throw away. I'll use the info and rebuild the coils for my Protank and EVOD. But an RDA is not in my future for a while. Thanks all.
