My problem is, I will send cargo money to China (60 USD for hasboard, 120 USD for complete S5), and it is up to them to decide whether it is due to bad manufacturing or improper use.
Besides the financial issue, I do not understand why there is not a third party , technical escrow service, who is paid by Bitmain but not binded them.
According to me, if Bitmain should not decide herself whether she manufactured badly or not.I see this not a financial problem but an ethical problem.However, if you agree with the warranty procedure of Bitmain, we are only protected with Bitmain's goodwill but not any written, tangible rules.
We own a mining farm with my partners.We own hundreds of miners.When you make an investment you want to limit your risks and hedge all the risks.Here, I see a risk.Obviously, the majority is fine with the regulation of Bitmain.
There are some problems with S5.It is due to firmware.When the internet is cut but power is on, the fans are not working (if you do not fix it to fixed value with the latest firmware update).There are also some controller problems, you can not access into the miner due to this problem.
There are also some problematic chips which do not work.If a chip does not work all hashboard does not work.
The badly manufactured miners are 5% of the total (for the 90 days period).When usage period increases, this percentage may increase (it increased for S4).
I recommend some solution:
1)A free third part service, financially supported by Bitmain but free administration.
2)An expert employed by Bitmain may come to large farms to perform checks if the farm owner pays the transportation and accomodation costs.
3)Bitmain may agree with local electronic services to make pre controls and service fee is invoiced to customers.

Your concerns are valid as a farm owner, but Bitmain has no reason to change their in-house quality control/technical assessment. If you don't like the way they do it, you are free to buy elsewhere (but unfortunately, nothing else is available). This is how free markets work, and at the end of the day if Bitmain adopted your suggested policies, all of their customers would end up paying more for miners (costs incurred are transferred to the customer). It may be a risk, but show me an industry/investment without its risks and I'll show you a liar
. Besides, from a financial risk point of view, the idea that Bitmain may knowingly and wilfully refuse warranty without cause is among the lower of risks IMO. The farm catching fire, hardware theft, power/internet interruption, crash in bitcoin price, these are the things I would spend my wakeless nights worrying about.
