Thus far I haven't had to adjust the pin much, the pin on the aerotank is just a tad too long but it still works. My Kayfun, Patriot, Igo, Iclear, Protanks, and squape fit perfectly.
I have to readjust the pin from the SBM every twenty minutes. I pull the pin up, attach my russian, vape, and then nothing. I have to take it off, and adjust the pin back up, and then reattach the russian. Its so frustrating to have to this so often!!! Any advice??
