Never buy anything important from Amazon, period.
I bought some counterfeit Shimano bike parts last year. They were a combination of two different models that doesn't exist in any Shimano catalog. I left a review accordingly, with pictures, and they took it down "after verifying with the supplier". Never trust the reviews, because they take down the ones that try to warn you.
Even when I get goods that are not counterfeits, they aren't as good. I have no idea how this happens but I bought some Leviton GFCI receptacles off Amazon when they were out of stock locally. I don't think they were counterfeits and had the retail box, all the stickers, everything and looked perfect. But the failure rate was about 50%. I had to go to my local Home Depot, buy the exact same part number, and they all worked. So even when they aren't counterfeits, there is some way where QC rejects are getting mixed in or something.
Never buy anything important from Amazon. Never buy storage media from Amazon. Never buy X from Amazon...the list of things that I WILL buy from them is getting shorter and shorter.
