Here's another fact for you to check....
Do you remember what the guaranteed hash-rate was when you bought your miner?
I'll go one better - I'll tell you exactly what my Jupiter was hashing at the pool when it arrived, (many weeks later than promised, many thousands of dollars worth of btc already lost because of that):
260GH/s
Is that 550GH? Is that 400GH? Is that more than I paid for? No x3.
And when I informed knc of this massively under-performing piece of shit (and I used much nicer language than that when I contacted them), did they go out of their way to help? Did they say they were sorry to have shipped me such a piece of trash? Did they try to come to any kind of compromise to fix it without it costing me thousands more? And did a company, that tries to pretend they value their customers, ever contact me via this forum to see if they could work things out? No to all of the above. They don't give a shit.
I think their own official forum exists so they can compile a list of people who are critical of them and then fuck them over should they need an RMA. It sure has nothing to do with answering customers questions!
Let's face it, knc are just another sleazy asic company who are only interested in taking people's money and doing the least they possibly can to fulfil their obligations. I'm pretty sure they were going to take everyone's money b4 Xmas. But once I wrote they'd be seen as greedy bastards for doing it, they went back and removed the line that mentioned "Friday" from their last newsletter

But back to the point. Now - are you & others going to continue telling me I got more than I paid for??
