In february I sent my Antminer D3, very good condition, to Bitmain for repair. Two boards were broken.
The miner was operated in a server cabinet. No dust and no moisture.
Today I got the alleged repair device back.
But that was not a new miner and not in the good condition as I gave him.
Everything is scratched and the heatsinks are corroded. The steel plate and the ventilation grille is also corroded to some extent.
I'm really upset. Since you give a good device and get a piece of scrap.
Who knows the conditions under which it was installed and how long it will last.
I hate Bitmain. They are cheaters.
The moment you buy their products,
you already agreed on their horrible terms of services
they are well known for this type of activities
a risk embedded together with Bitmain product
