defective protank heads

[The Batman]

So I received my new protank heads and there is less threading that screws into the base than on any of my other heads. They screw into the base crooked and when I try to screw the base onto my protank with these heads it won't screw in all the way. Not even going to attempt to fill with liquid as I'm sure it would leak. Anyone ever have an issue like this? I have a feeling these are knockoffs. Waiting to hear back from the vendor I got them from.

sorry to hear that. I haven't had that problem but all my atomizer heads are kanger. good heads up to check fitment before I rebuild them. that would be a waste of time.

Well, I got three out of the five heads working buy messing with the o rings a bit but there is no hope for the other two.
