I'm running a set along side a couple of pairs of HE2 in my Sigelei 100W. So far after a few weeks of use, they last a little longer but nothing significant. Not enough to justify the extra cost over HEx or 25R for me. This is vaping at between 60W and 80W.
Different mods and different vaping styles may give different results though. Glad I tried them, and I might pick up another pair to try in a parallel mosfet box (when I get a decent one), see how they handle themselves unregulated. As it stands, I'll be buying green 25R from now on, unless I need more than a 20A CDR.
