UPDATE

After asking B+W a second time for a reply, I received the following from them, hence 5 stars to B+W who recognized unit was defective and acted on it, and zero star if possible to B&H who didn't do anything but stating warranty was no longer valid, hence letting a customer do all the work to have a fair treatment.

Hi xxx

Authorization has been given to replace your polarizer.
As your version has been discontinued, we are sending the replacement under part # 66-*******. This is an 82mm MASTER HTC C-POL MRC NANO.
I am sorry for the delay. Please confirm the address on the receipt is still valid, and we will ship.

Original review follows:

Living in Canada, I bought from B&H Photo Video a B+W 82mm XS-Pro MRC Nano Polarizing Filter which with the time developed 2 issues. It is systematically falling apart every few hours of usage or so and there is a "delamination of the polarizing foil from the glass surface" as diagnostic says that now progressed enough to shows on pix when I shoot at F22. This filter at 150 $USD should have never pass quality control. I didn't returned the filter in the 30 days as I was in the field and then the 1 year warranty period for various reasons (pandemic meant much less usage and I kind of resigned myself to re-screw the filter regularly as needed). Not sure this filter was used for more than 8 weeks total. Rep in Canada who did diagnostic told me "we suggest you take up this problem with them" aka B&H. Yet B&H refused to do anything saying B+W warranty is 1 year. So I wrote to B+W USA and got the following as a reply: "we do not warranty B+W product sold by B&H, as they choose to buy from a source other than Schneider Optics. Any resolve on this matter must be handled through B&H"

So
B+W rep in Canada says B&H shall address this
B&H says on the phone nope more than a year sooooorry and no further support…
B+W rep in USA says "this matter must be handled through B&H"
What a bunch of complementing crooks! Both B&H and B+W are accountable in this.
This is what I wrote at B+W in Germany in a last attempt.
"This address www.schneiderkreuznach. Com appears on the filter box and it appears in the email I have received down below, I'm sorry but that seems your company is not taking their responsibility seriously. Is there anything that can be done? You cannot sell faulty products that shouldn't pass quality control and wash your hands and walk away like this passing the ball to one another saying cowardly "not my problem".
That's nonsense!
Conclusion, AVOID B+W overpriced filters that delaminate and fell apart and avoid buying from B&H as if you have any problem and don't send everything back immediately (hence forbidding you to shoot) you'll lose your money and end with degraded quality of pix eventually. It's just a matter of time.
