You say "20% safety margin" and I think "20% overclocking margin." 
Whoa! Stop the press... that sounds like something an end-user would say, not an employee of Hashfast.
Furthermore...
IMPORTANT UPDATE
HashFast customers opting for the Miner Protection Program will receive their additional ASICs already assembled onto mini-boards.
Hashfast, the company, apparently wasn't fully onboard with this... as evidenced by the subsequent post by Amy Woodward
only two hours later:
This statement needs to be clarified and was released prematurely. We are currently in the final stages of an internal discussion about how to further protect miners moving forward for customers that opt into purchasing it.
So, tell us, are you employed by Hashfast? Will someone from an official Hashfast account confirm that? If not, you're some form of unaffiliated shill. Are you cypherdoc?
If you're not officially affiliated with Hashfast, the moderators should change your name. Hashfast employees, what's the deal?
