Okay so I've had my Eleaf for a while now but recently I have ran into a problem. Now when I try to screw any tank or rda onto my mod it will start screwing and it will read the ohms but when it hits the mod and is all the way screwed in, it will keep on screwing for a bit and I can hear it scraping across my mod and when I tighten it all the way it will not read the ohms. Is there any way to prevent this?
