So I'm a newbe again. I've been a poster and commenter on ecr for over two years and thought it was time to figure out ecf. It seems I need to make at least 5 posts in the new member section before I can do any post or comments on any of the other threads. I do my own DIY and have been doing it for about two years. I own a Sigelei 150W TC, 100W plus and a mini 30. I like Sigelei products because they work. I also own an Atlantis V1, V2, Triton, Kangertek Geni tank regular size and a Uwell Crown black. Since getting the TC device I have completely stopped using the standard coils and just use the ni200 coils. I think TC is the best thing to ever happen to vaping.
