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!
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 ?
So first of all. I'm from Europe.
I had troubles with them with invoices and some administration. At the beggining I had spoken on phone with Andreas, he promised me something.
When the shipment began, I had some troubles too, but I alwas had a reply for my e-mails, and when I told them about the situation 4 month before the shipping and the promise of Andreas they solved my problem asap (in one day). But it was only a promise and 4 months.
After I received my box, I had contacted them severel times by mail, I had got answer max in one day.
When I told them that is something wrong in the fpga handling (they wanted to start rma the boards, but the failure was not there) they answered back. Something like that: hey guy you have right, we are working on it.
After the first few firmware issues I didn't had to contact them cause everything worked fine.
On the other hand, there are the die 0 issues, not working DC-DC-s.
I read every post in this fu---in topic. From the 1st until now. There were a lot of bitching about rma "yep I have to pay 200$ to send back" yep yep. Guys, these are machines manufactured buy humans, always wil be problems. Rma is to solve them. You buy a machine for 7000-10000$ and you bitching on 200$? (And this machine makes money for you)
Something like kids do on the playground.
Just one question to everyone: Did you do your best to solve the problem?
I think lot of here yes, and a few no. But the few is the loudest.....
I spent 3 days and 3 nights after I received the miner to make it stable. If I should have had a faulty card I've askd for rma the day I discover it, the next day day I'v sent back with overnight shipping, I'm sure I got the new one the day after.
Delayed delivery was in the play when you ordered it. You had to take care about it. But it was not 3 or 4 months..... Sorry to write that, but in these days this is the asic business. If you have fear just don't jump in.... It's simple.
Rising difficulty.... Say thanks to Bitfury.

He made his best and made it well. It was not good for us but it's an other question.
And yes, I will order from KNC some gen 2 devices. I had no problem with them. But if I got faulty miners, I'll try to do my best, if I can't solve I wil use rma.
If they late with shipping or something go wrong: It's part of the game, deal with it.
In these days mining is not money printing like avalon batch one. Marginal profit, and a lot of risk. If you lucky you earns some, if not loose some.
So I can only repeat myself, if you can't deal with risk don't jump in and sit on your money.
I know some guys will hate me when a write this, but this is my opininon about mining and asic industry.
