hello guys, four months after I bought the miner from Bitmain, 4x S5, I have burned 2 cards, fortunately still had the guarantee, and we resolved, I am now five months that I use the miner, then the warranty expired, and a blade has burned, I asked for help to bitmain saying that I wanted to buy a new blade, they said they have no more spare parts because S5 is out of production ,.
I do not understand what kind of support you? in 5 months you were burned 3 pcb, now do not even spare parts, no longer respond to email me, if you burn more blades so I can stop undermining bitcoin, because there are no spare parts? so I paid $ 2,200 including shipping to Italy 4x antminer S5, I have not made even half of the investment, I burned the miner, and I can not replace lame.ho asked a cupon to buy s7 least to compensate the crap that makes bitmain. I think that the products bitmain are scarce, if you burn in a few months.
