I use these Coilology MTL Aliens in all my MTL RTA’s. I have tried the Coilology MTL Fused Claptons and these Aliens have slightly better flavor but I would still recommend either. The only con I would give is that they list the Ohms as .84 per coil and I can tell u after using multiple containers of these that they actually ohm out to .65 Ohms consistently not the listed .84 but that’s not a big deal for me honestly…I vape them at around 20 watts u can go higher or lower no problem and they perform great in all my MTL RTA’s….I will say I wish Coilology offered a version of these made with Twisted Messes (TMN80) wire like they do with there dual coil aliens that they also sell but hey u can’t win ‘em all lol.
