  • Quality at a great price!
I have three of these so far, bought from Nick at his family business, Ing Mining. Products are used, as he says, with scratches and dings, but they start right up and are mining in minutes. Excellent buy for this price. Not efficient enough for the huge mining farms anymore, but perfect for someone with a dozen or so units as a hobby. Thanks Nick! ... show more

  • can be in very poor condition - prone to failure
Item worked for a week then died completely. Not in "very good" condition. Contacted seller repeatedly and received incoherent responses. Seller unavailable by telephone. I have to also say this was the second one I bought from this seller and the first one is still running after 2 months - and appeared to be in better condition. I was able to return the broken one, which is wonderful. ... show more

  • Quality used hardware
Arrived as stated. Works well. Came with Braiins Firmware. Will need to revert to factory or another pool if you do not want to use Braiins. Chips on all 3 boards were healthy. No sign of prior abuse to hardware.
