No alternatives were offered. Liam was very adamant over the phone, not even giving a reason why a BTC deposit is not a viable option. He just said: "we are not going to change our RMA procedures" in a way that made it clear they don't want to work with their customers.

Sending it back is a risk I am not willing to take: it can take 3 days, it can take a week. The lost revenue while my machine is offline will never get recouped back from the increased hashing performance. At least not at this stage.

With the network roughly 4 TH/s, 70% would be 2.8 TH/s, or roughly 5000 Jupiters. But they shipped a lot of units slower than Jupiters. So lets say roughly 10,000 units shipped. Is that in line with their shipping announcements?

4PH*

2.8PH*

That is quite a bit of Hashrate but understand they though each unit Jupiter would originally only do 350GH or 87.5GH/Chip

Let's assume they had 20,000 Chips - 1.75PH




I'm assuming they are talking about Chips

I believe BFL has the next "Most GH Per Chip" (Regardless of power consumption

BFL Chip - 4GH

550 4 = 137.5
KnC Chip - 137.5 GH

3437.5% increase

 


Yeah, the "profound effect" was the sky-rocket of difficulty, a very important factor which should be made aware by them to every new customer. However, they are more interested to make this stupid statements and keep hidden the real facts, which in turn will guarantee the sales of more and more devices to misinformed customers.

By the way, the "state of the art" is another marketing bullshit. The firmware for their products is still under version 1.0. Moreover, as evidenced by this topic, many KnCminer customers had to open the "miner" cases and deal with internal components to guarantee the product would work as best as possible. The promise of a plug and play product never came to existence. There is not such thing as "state of the art" product among KnCminer offers.

Now, where the "3600%" statement come from, I have no idea...

The plain truth for most people is that without the current rise in the price of bitcoins we'd be crying. KNC will be doing well off that too, both from orders paid in BTC and from their own mining. They can't seem to lose...even fucking shipping made them a profit ffs. 

No, I expect when my customers and I spend 10k+ on a machine, regardless of the industry, to have support to go with it. Ive been in the IT industry my entire life, and not even HP's RMA process (one of the worst in the industry) is on the ultra-low level of KnC. Ive never seen a RMA processes handled so poorly in my life. No communication, no flexibility, nothing. I would NOT buy another product from this company, not when they are too busy talking about the next thing to fix their current product. Im surprised paypal has not nuked their account from Orbit.

I expect advanced RMA when dealing with something time sensitive, let alone expensive. My dell's have a 24 hour turn around time, IE I get replacement parts within 24 hours or I get some serious compensation. Especially since KNC only sells to "businesses". You think any real business would put up with this kind of crap from one of its suppliers?

I have to second that.  It took me over a week of playing the game of "answering stupid questions one per day" before I finally managed to get an RMA-number.  Now that I've returned the defective module to them, I've heard nothing - zip - zero for another almost two weeks.

I should have had a replacement module in my hands the day after I reported it as being broken.  But no, it was "For today, try it under firmware version 96.1 and tell me what happens" - still doesn't work.  Next day "We'll be releasing firmware version .98 tomorrow, try it with than and see what happens" - still broken.  Next day "Try running it for 24 hours to see if the problem clears up" - still broken, and on and on, etc., etc, etc.

Wow,

Now we have actual timelines on the RMA process. Most people are complaining before they even send them in.

Thank you for including a time frame. Are there others out there that are having a similar wait time after sending in their unit?

It would be nice to collect actual data instead of conjecture and emotions.

I'm going to swipe bobsag3's response and respond...

Depends on what you call "under performing."  My module would run for almost exactly 30 minutes at 70 Gh/s and then shut the machine down.  Period.  Had to power off and back on to get the Jupiter to come back up.  30 minutes later, dead again.  I isolated the problem to one particular module, even swapped it into another machine - 30 minutes later, machine dead.  Running the module by itself - 70-80 Gh/s, and machine dead after 31 minutes.  Tried every version of firmware - same result, module would run for 30 minutes about, then kill the machine it was in.  Every time.  Every version.  Every machine.

I couldn't seem to get the point across to customer service that the module would run for almost exactly 30 minutes, and then kill the machine it was running on.  I spent a week trying to explain the problem, then finally got fed up with it and "strongly requested an RMA" after playing "what happens if" games for a week and a day.  Returned the module, and it has disappeared - no acknowledgement of it arriving, no status, no return shipping info TWO WEEKS after the tracking number shows it was in their hands.

Everything that's come in has gone out. What's the RMA? I'll look into it.
