Great information thanks so much, I have begun looking through it. Husband has a ohm meter and made a coil that was 2ohm and used cotton and WOW what a difference it made! My favorite juice tasted better than ever. I think I dont like silica taste much. Your right it IS so satisfying AND fun to build. After kids go sleeping all we do lately is read and watch videos about vaping, we are having a ball. The Kanger had a huge problem with flooding maybe this will cure it. Again thanks for your support.
