Bests & Worsts Reviews from Amazon

Bought this and the XS-Pro and both are fakes. They're good at it too as both came with the hologram, all the stickers (even the self-marking one on the plastic storage box), felt heavy like brass, and "appeared" to have the lettering engraved on the inner metal edge of the filter. After reading the reviews I knew to be cautious. Upon inspection, there was a different tint to each when held under a lamp at an angle. One a bluish color and one a dark green. After spending hours on forums, I read that B+H and Adorama are authorized dealers. THEY ARE NOT. I called Adorama as they are a supplier for Amazon and asked if they were an authorized dealer to which the rep replied, "Yes, we are". So I placed an order. That one came with a lighter green tint than the exact one from Amazon and it felt much lighter. By this time I've wasted waaay too much time and effort on an unnecessary (debatable) UV filter. I called Schneider Optics, the parent company of B+W, to get some clarification. They informed me B+W no longer uses the QR scanning method to verify authenticity, that they are aware Amazon mixes their filters with other suppliers and are working to correct the problem, the plastic boxes no longer come with the self-marking sticker, Adorama and B+H are NOT authorized dealers and sometimes sell "grey market items". So even if you buy one that is "Sold and Fulfilled by Amazon" like me, there's no guarantee the filter you get will be authentic. I finally ended up finding a dealer on Schneider's website. It cost $15 more but it's the real thing and that's what I paid for. After all this hassle, the best way I've found to check is to take a toothpick and feel for the engraving. The fakes are painted and it's very hard to tell by sight, but on the real ones you can feel it. Hope this helps someone.
