The threads on that one are not compatible with most other nemmys. Wouldn't buy a FT nemmy for under 15$. Quality suffers. I have one of the supercheap nemmys, and right now I am running it in 18350 mode, with an inline ohmmeter. Any other configuration is unsatisfacotry.I'd bet you'd really like that one JK. I had toyed with the idea of one, but I'm sticking to my guns and limiting my mod purchases to replaceable batteries now. I even picked up a Nemesis mech from FT. Merely because it was about $8. I have all three battery sizes, so it becomes a 3-in-1 device for me....
