Has anyone rebuilt them yet? I gave it a try and was not really to hard. 1st attempt I wrapped Japanese cotton around it and was to thick and blocked the hole and flooded. Second attempt I did 28 gauge 8 wrap, wet some cotton with juice and wrapped around the coil not to thick and with a tooth pick placed through the coil and cotton wrapped around it I slipped it down the chamber, put it together and fired up at 1.4, no flooding and flavor was just as good as a new pre-made coil. it's that cotton pad there using around coil that's turning black after a few weeks that causing the need to change to new coil . Anyhow, you guys have any thoughts on that, I did not find it had to be to packed, key was to not have the hole down center of coil blocked
