First of all, Thank you all for replying,
I do understand your point of ordering from trusted 3rd party store like Amazon but the issue that this point only cost you in this case over 250 USD, So is it worth it or going direct to the supplier or official distributor at least.
The second point that these minors are functional and exist not another fake china product because it is over a multible known website for evaluating miner value like :

I really thought I can find a certain answer here as this is our larger Cryptocurrency community in the world
Anyway, I will wait and see if someone who more details or have any certain facts.
Regards to all
