So after a LONG wait thanks to Chinese customs, I have finally received my K3m clone yesterday. Had a good play around with it, made three builds for practice as it's my 1st RTA and actually made one I felt was decent and didn't fail miserable at the wicking.
Lo and behold, 18 hours after I started using it the 510 pin has stripped and will not hold the square plate in place. Those who have seen it will know that I do not mean the part that screws onto the mod, as that is the square plate, but the pin that makes the positive connection as well as holding the square plate (the negative connection) to the mod. This has rendered my precious unusable. I even got desperate enough to try kitchen foil and supergluing the airflow grub screw onto the 510 pin to extend it, but obviously this failed.
It was completely fine for the 1st 18 hours until I acidentally knocked it off the table when it on my charging ICF4, and hit the floor atty-down. I'm assuming the fall made it push past one of the threading grooves and strip the 510 connector pin ever so slightly but enough to fuck it up, as it was loose after the fall. I tightened it but about an hour later my 1.3ohm coil jumped to 3ohms, I took it off to check it and was realized the pin was just spinning in place when I tried to tighten it again, and I could take the square plate off just by lightly pulling it off as nothing was holding it in place. I don't think me smashing it down to try and force it into the threading helped either tbh
This is more of a rant than anything else by now tbh, but I have now ordered another one (along with a Derringer clone) as extensive google-fu turned up just one post of something like this happening, making me think it's not something common. I certainly never heard of it researching the atty and clones beforehand. Was I just incredibly unlucky, and should take more care with the next one? Is it possible I recieved a defective product (unlikely IMO)? It was cheap and I've fucked with it too much by now to even try and return it (i tried sanding off some of the square plate to make it thinner and get the 510 to screw in deeper
) just not sure what to expect with the next one. Any input appreciated, now time for the waiting game once more

all this after my order doing the Guangzhou roundabout for 2 weeks, then stuck at Chinese customs for 3 weeks before being rejected for no reason and having to wait for them to resend it with Hong Kong post.
