    Another great experience dealing with Parallel Miner! Item was as described, and shipping was on point. Thanks again!

    I was extremely impressed with the customer service and contact along the way, when paying with cryptocurrency added communication always makes the buyer feel a lot safer, this was one of the more expensive crypto purchases that I have made and it made me feel good to have steady contact and professionalism. The minor was tested and ran for several hours depositing its earnings into my wallet/pool which I’ve never had a company do for me.
    I will say I was slightly disappointed when the unit arrived and some of the screws were a little stripped from changing the fans (which were NEW). It ran at full hashrates as advertised, and was purchased as used so no real complaints. I would buy again but for the price a power supply should have probably been included

    Fantastic experience, even with issues. First miner arrived with Asciseer installed. No big deal, I use Braiins OS so it was an easy switch to match my other S9 – just a quick reset and sw load. Right out of the gate I was getting auto tune errors, breaker tripping, nothing wanted to work right. Reached out to PM and explained what was going on and they sent a replacement the SAME DAY. Unfortunately the new one arrived with a busted fan (FedEx used the box as a speed bump a few times). Swapped the fan over and voila! Perfect. Returned the defective one and busted fan and I’m good to go. Excellent company, people, and outstanding support. They earned my future business just by how well they helped get everything right.

    It’s completely useless, since I can’t login to it with root/root. Not sure what to do and if it’s returnable

    They sent me a miner with a bad hashboard. Upon firing the s9 up only 2 of the three hashboards work. The red light on the third board wouldn’t even flicker so it has to be a dead board. . Definitely disappointed only getting 2/3rds of what I paid for. Not cool

    These s9’s are getting old. There’s no such thing as GEM units left unless they are brand new. So I feel that is bad advertising on there end as they clearly did not send me a gem unit like they advertised and I expected. If they did I’d have a 100% working product.

    We will see if they honor the warranty request if not live and learn right? This is expected when you buy used electronics
