Antminer S9 Bitcoin Miner

Buen producto como nuevo. Lo recomiendo

Miners arrived on time and all functioned at advertised hash rates. Miners were pretty dusty but that is what I expected as these miners are quite old. Price is a little high too.Overall, I would buy from this seller again.

Miner came new, clean, good shipping package, the miner had the firmware and a simple IP login to start mining with my pools added, this was a good deal, will buy again.

Something was loose but it still works so I’m not sure if that “looseness” is normal. I’ve seen it clock at 9th/s but I’ve also see 19th/s for a short period of time. Average is about 9th/sec not sure if this is a quality purchase but time will tell

it works well, I arrive in good condition, it does not have the 5 stars just because it has problems connecting from a switch

Excelente

Ordered 3 machines from them, 2 work great and the third is defective. Nothing but games and no help in exchanging the unit. Will never buy another item from this seller.

I received the unit with major defects and poor cleaning as the photos show. After receiving my power unit and getting the device up and running it became apparent the device was almost non-functional. Not only did I not even come close to the promised 12.5 TH it also had internal damage which sounds like a loose heat sink. This specific seller sold a DUD and I would avoid them at all cost. After this fiscal I purchased 2 relatively new ones then deal with a seller that promises to ensure the used unit is it as at full operational status but fails to deliver that. This is my updated edit from my original post around 5/15 time frame.
