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 ?

Are you guys kidding?
I was contemplating a November Jupiter...
and went thru the numbers, and made all the predictions in my usual way, and I came to the conclusion, that a November Jupiter is definitely worth it, and spent the 17.6 BTC, of my 27BTC I made in the first 20 days, to order it moments ago....
And I'm stoked about it...
Think about it...
The November units may even deliver before HF & CT get their act together!
