What is the big deal about a spring loaded pin? I see comments about it quite often. Im not being sarcastic, I'm honestly not sure of the big deal. I think most of my mods do not have spring loaded pins and they seem fine with an array of tanks/RDAs
I refuse to buy a box that doesn't have stainless 510 threads and a spring loaded pin unless it can be fitted with a proper connector that has those features. The physical and electrical connection between a mod and atomizer are too important to accept soft threads and fixed pins.
I think I saw a video on the tube somewhere, on how to install the FD connector, might not be a Sigelei mini. However, it's the same/similar procedure.Nice setup is that a FatDaddy you put on the MVP 2? I'm trying to hack one into a Sigelei mini for a friend as he trashed his threads.
The subtank pin is not spring loaded. It uses a rubber grommet to locate the pin which gives a little. Fixed atty pins are fine when the mods pin is sprung.
