I ordered two second-hand Jasminer X4s

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.

I purchased 2S19 90T from Cooldragon. Although my address is very remote, they just charge a reasonable shipping fee. I also received the product quickly, and really appreciate Cooldragon

I ordered from them for the 4th time

I ordered from them for the 4th time. I purchased 5 KS0 PRO this time, and as always, delivery was quick. If you ask me, Cooldragon is highly recommendable.

New ks1 miners

Good miners, ship fast, very good.

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

iceriver ks3m is very good

I bought 2 pcs ks3m(nov 15-30batch) from cooldragon. The seller shipped the goods promptly within December, allowing me to receive the products quickly. The machine runs as expected. I think this seller is very good and I will buy again.

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.

Smooth transaction, would buy here again

I purchased five Iceriver KS0 miners off cooldragon.io and they all worked as expected upon arrival. Zero complaints and I would order from them again without any hesitation.

DOA used miner

I ordered a used KS2 and when I received it two the fans did not work and I was not able to find it on my network. when I contacted cooldragon they asked if I had any fans I could replace them with because that could be the reason why it’s not connecting. So I replaced them with one week old fans off a different miner. All fans are now working, but I cannot connect to it or find it on my network. They had me do several steps to attempt to fix it to no avail. Which were the same steps that are put in the manual which I already did, but I did, and recorded all video to share with them. In the end, they told me I need to ship it to iceriver to have it repaired. I find it hard to believe that this minor worked when it left their hands. So now they want me to pay to have it shipped to iceRiver and shipped back to me. They did, however say they asked if iceriver would do the repair for free, but more than likely the shipping is way more than any part it needs. And also asking and having it actually free are two different things more than likely I would still have to pay for the parts and who wouldn’t if it was already sitting there in the repair shop. From what it seems all it needs is a control board. They were very nice with communication, but it seems they have done as much as they would like to do.
