That is completely unreasonable. Ambient below 72F ? WTF is going on over there at HashFast ?
HashFast is very busy assembling the first batch of true 3rd gen Bitcoin mining hardware.
These miners are not intended for home use. In other words, commercial use only.
They aren't set-top boxes or your Playstation. They need to be hosted in a temperature controlled environment, not your basement/garage/attic.
"Unreasonable" is expecting heavy-duty professional grade hardware to run reliably in an ad hoc amateur setup.
"Unreasonable" is buying a supercharged Cadillac XLR because you want the high-compression 443 hp engine, then whining because it only takes premium gas.
You continue to not understand how to properly deal with customers. I think you really could be a stealth HF account because you have the same poor understanding of customer service that they are currently displaying.
No one invests $48,000 in BTC in a Playstation or a set top box. Spending that much money does come with an expectation of service from the company you have given your money too. People who buy luxury cars DO complain when there is a barely visible NICK on a part of the car.
Regarding your 72F comment - these boxes WERE INTENDED FOR HOME USE - they were sold as watercooled, low ambient temperature hardware that an enthusiast can purchase. Professional grade hardware does not come in a mini-tower form factor. The Sierra is a 1U - it goes in a rack, that's for a data center. No professional anything buys a mini tower. If you think BabyJets are heavy-duty professional grade hardware, then you know nothing about how the real world. I'm just lol'ing here imagining if my Dell rep every came to me and attempted to sell me something non-rackmountable for our data center.
Furthermore, the "unreasonable" update level was exactly what they were providing last month - updates were frequent and official responses were plentiful. It was only when things got busy that customer service got thrown out the window. I get that "they're busy working on our hardware", but the customer service skillset is not the same as the hardware assembly skillset, someone is not doing their job here and should be.
