I'm using 316l, but I'm unable to get it to work on either the amok kooper plus or the xcube 20. It works fine on my hcigar vt200 though so I just don't think the smoks like it! I've seen a couple of you tube videos where other people have the same issue, it says its limiting the temp, but keeps firing anyway.in my case it just never seems to limit the temperature. Gave up in the end, the hcigar does it perfectly.
