For the trolls: I'm a happy customer. 
I had to play a lot (it was fun) but I have 570Ghs and my investment back.
Right on!I had to play a lot (it was fun) but I have 570Ghs and my investment back.
One could get the impression there was a statement like 'no happy customers at all'.
I'm happy for you that it worked out so nice, that you do not need to pay this f'ing -/+20% Tax like us Europeans, early delivery date, smoothly working devices and therefore reached break-even. Honestly this is great. I know there's always one in the world doing better than me, so I'm totally fine with it.
If nobody would have reached break-even, situation for me would be worse for sure...so really nice!
However I'm confused that you do not care even a little about others suffering (not me).
Didn't you consider further business with KnC ? How about next time it might be you punished by bad luck with delayed/messed up delivery, broken miner, delayed RMA, nobody picks up the phone, several days of exhausting email ping-pong while diff increases and other stuff reported...
And this is exactly my point.
Nice it worked out! But what's next time ?
For what it's worth: I do care about others still suffering of not having received their miners in time or Not working. When I received my Jupiter I can remember very will the despair of a not working Jupiter (only 350 Ghs): I really lost all faith, and felt scammed again after my BFL disaster...
But the sky cleared after KnC released their 0.95 FW (thanks again KnC !), and I'm hashing happily ever after. I currently have 25 Coins which gets me after 4 weeks a Breakeven in Dollars. Nice, but I realize that this is just luck caused by the price explosion of BTC. I realize as well that I will probably never break-even in BTC terms (for that I need at least 60 BTC, which will not happen). So be it...and I don't care.
What I believe is that BTC will be 7000 dollar one day (just 1% of Gold's total market cap), and by then any Jupiter (also your late delivery, or subpar working device) will have produced at least 1 Coin >> Break-even in dollar terms for all of us ... and a great journey (you can tell your grandchildren some nice stories...)
