Do not use this Company!
This company did not properly test my hashboard and went ahead and removed a chip without my consent even though he told me that he would not perform any work on the board if there was a bad chip. He claimed that non of the chips were hashing when he tested it, yet that was not the issue I was experiencing at all. The board would hash for several hours every time it was booted and then stop hashing. Without communicating or proper testing he then removed one of my chips and replaced it with a bad chip. Later he told me that the control board he tested it with might have been bad so he would try installing the original chip again but that did not work supposedly. I don’t know if I even got my original chip back as the Z15 chips are going for $800 online so it might have just been stolen and sold. I now have my hashboard back with the same issue but one less chip now. I highly recommend not using this company.

Dear Tony,
Thank you for your review. Unfortunately, it contains several inaccuracies. Let me clarify the facts based on our full conversation.
1. Condition of the hashboard upon arrival
The board arrived with one shorted chip. It was showing 000 with 0 kSol/s. This was confirmed by diagnostics and thermal imaging. You yourself wrote: “It was showing 000 but hashrate was 0 kSol”.
2. What was done
I replaced the shorted chip with a working one (from my stock) for free so the board would at least run partially.
The other two chips were never touched and remained stable.
Your original (shorted) chip was returned to you on the board.
3. Repair policy and your consent
By placing the order you accepted our standard repair terms (stated on the website and order confirmation). These terms allow us to perform all technically necessary actions to restore functionality. I offered you multiple times to issue a full refund and return the board as-is (even though payment had not been made yet). You chose to proceed with the repair.
4. Final result
After the replacement the hashboard worked stably on 2 out of 3 chips. The later drops to xxx were caused by additional issues (controller board, power, etc.), not just the hashboard. In the current total shortage of Z15/BM1746AA chips, achieving stable 3/3 is not possible.
5. Payment
No payment has been received for this order (#1508, status: Payment pending). Despite this, I performed full diagnostics, chip replacement, and testing.
I understand your disappointment - you wanted a fully working board. However, replacing the shorted chip was necessary; otherwise the board would not work at all. Everything was done transparently and in your best interest.
I can provide all screenshots of our correspondence, photos of the shorted chip, thermal images, logs, and diagnostics to anyone who requests them.
Alex.
