I managed to kill f3write, so f3probe could access it:
ene@coyote:/mnt/disktest$ sudo f3probe --destructive --time-ops /dev/sdm

Bad news: The device `/dev/sdm' is a counterfeit of type limbo
You can "fix" this device using the following command:
f3fix --last-sec=124050943 /dev/sdm

No faster than it is, its not worth the f3fix effort, I can buy
reputable, much faster sd cards at 1/3rd the cost.
Okay -- here is the thread Thomas referenced. It has not hit the
archive servers yet.
The f3probe results are bad news, but not unexpected. At least you have
a definite answer that you can send to the seller and/or Amazon (?).
