With B&H I have never had a problem with respect to questionable product, always new. I did have a DOA lens once, Nikkor AFS 85mm f/1.8. They took care of it.
Sidebar comment.
Within the last year, the movie "The Abyss" came out on blu-ray / 4K UHD, a long, long awaited treasure for those of us who like the movie yet were told for years on end "next year they will release the movie..." and it never came.
Finally, this year. it came.
When news broke late last year, of it's "true" release, which also came with a special edition one-night showing in theaters (to which I attended), I pre-ordered the movie on Amazon as well.
The release date passed and received the movie. It turned out the 4k UHD version was unplayable. Thinking it might be a shipping issue, because the 4k UHD was not secured to the hub inside the plastic movie box. it was loose. It also looked like there might have been scratches on it, which "could" make it unplayable (happens sometimes no matter who you get the movies from), I started a return with Amazon.
During the return process, going through the screens (like a normal return) it felt a bit different in this case. By the time I got through the return process, the last screen, it stated "We can't take it back" so the ONLY option was refund my credit card, with a message no need to return the product. WHAT?? SURE! I took it.
Within a day or so, with no responsibility to ship back the movie, my card was refunded.
So, whilst I had an unplayable 4k UHD version, I ended up with a regular blu-ray HD version that was absolutely free. WOW!
We're NOT done with the story.
But I wanted the 4k UHD version, and went to buy the movie again, going to Amazon, of course. Yet this time, they were all sold out, with a message "Unavailable", not out of stock with an ETA date - like normal.
This was very strange. I hopped over to Best Buy, they did not have any in stock. But Target did. So I purchase a copy from them.
I got the movie. Same thing. 4K UHD did not play. AGAIN!
I started the return back to Target. And... They could only refund the money, they too, did not require a return. Now I had two playable blu-ray versions, for absolutely free.
Could it be the manufacturer pooched the released? Seems so, but I want my 4k UHD version. Eh, let me try walmart online. of course they had it.
I received the walmart copy. That was dorked up too. Same thing, no need to return it, refund in a day or two.
So, I sat with 3 dorked up 4k UHDs and 3 playable blu-ray copies. All for free.
At this point, no one had it for sale, all unavailable... Yep had to be a manufacturer defect.
I sent my friend a copy for free, he was just plain old happy with the blu-ray, just like I was.
To make a long story short, the manufacturer re-released it. I picked up a new copy and it all worked. just fine.
and so it goes.
