The videos were not sent, and in the end 4 of the five machines had problems. 4 hash boards are completely dead, and another 5 overheat enough that I don't feel comfortable running them until they've been repaired. The machines had rusty fan covers (so humid operating), and hadn't even been dusted with an air compressor.
So now i have one working machine for the price of five!
Going back to AKMiner and speaking with Joyson, he did have videos and sent them over finally claiming they didn't send the first time he tried, and four of the videos show machines with exhaust temps in the high 70C and low 80C.
This is their fault and not yours. They should act responsible and facilitate the return and refund for the damaged miners, anything less than that shows unethical behavior and fraud.
Someone else today had some complaints about the same company
I would never deal with AKMiner again and caution any and all to find an ethical vendor, of which AKMiner is not. I ordered 2 DR5s from AKMiner in July. After I sent payment they cancelled the order and claimed they never received payment. I’ve sent them screenshots of the payment, the transaction ID on the BTC blockchain, and six months later, I’m still waiting.
