just got this today in the mail from ft https://www.fasttech.com/products/1411/10005381/1438500 and i put my nimbus clone (from ft) on it and put a panasonic cgr18650 in and it wont fire, aswell as with a efest v2 30amp, and i tried with an aga t2, my floating pin has a hole in the center with threads down into it which i couldnt see on anyone elses, also it says it comes with brass contacts but my are silver, or atleast plated. nimbus and aga work great on m16 and private v2 with same batteries. also a lot of play in the batt tube when 18650s in it. i think my pin isnt making contact with my devices or switch isnt making contact with battery. i cant tell but id rather not have to send it back and wait another 30 days from ft.
