DX Engineering does stand behind their own brand. Always.
W3LPL said they were all OK as well.
You could have asked me in person when I saw you Saturday.
You should read the patent. It's available on line.
If there is a problem, you can email me directly and I will take care of it.

Any experience with DX Engineering PL-259s? I bought a half-dozen crimp
type for RG-8X, on the theory that DXE would stand behind their own name
brand. They are even stamped with a DX Engineering patent notice -
like what's to patent? They feel a little lighter than WW2 surplus,but...
