I'm very satisfied with the KS5 Pro 21T miner, it works well. The initial setup was a bit more complicated than I expected, but Ken kindly helped me to make the whole process smooth.

I spoke with Tania about the details of the KS0 Ultra miners, and after our conversation, I purchased several brand-new units. The quality is excellent.

I ordered two second-hand Jasminer X4s, they've been running exceedingly well, and yet they are obveriously much cheaper than a brand-new one.

It is not easy to buy miners online
It is not easy to buy miners online. There are too many scammers. I have been defrauded of tens of thousands of dollars by other websites before. This time I bought a miner from this supplier under the introduction of a friend, 1 pcs antminer ks3 9.4T. After payment, I received the machine in 8 days. Very happy to finally find a reliable seller

Ordered two ks0 miners
Ordered two ks0 miners. Answered all the questions i had, i received my miners in great condition. Only drawback was the shipping time, was some days that my order just said "processing". Other than that, fast and easy.
