Scam?

Lets face it; Bitmain is in it for the money.  Capitalism Rules in communist China.
While they have a great track record of customer service, Bitmain has not been entirely honest with their customers and distributors.
Watch your 6 when dealing with these chinese based companies; greed is a powerful motivator.  Your interests are of no concern to them (unless you have a wallet full of money).

Your an Honest man.   +3 to you... 
I think they should take back the coupon, and then send you a BITMAIN T-Shirt for being so honest.
Then send me one as well for suggesting this.   

Probably   

You probably right ChuckBuck.
Ninja wrote something about having new/used units available, so I thought he might have them in stock.
Why do you think the S1 are geting hard to find?  Bitmain stop making them?

I think Ninjatech has S1 in stock

Your looking in the wrong area.  Check your cards for cold solder joints.   
Symptoms you describe are indicative of this....  "leave it switched off for 30 min or more and turn it back on for some 5-10 min it hashes normally until the errors come again. "
Your ciicuit simply Heats up then errors begin because of the added resistance from the cold solder joint.

Cold solder joint looks Dull compared to a normal solder joint.  Sort of like a stainless steel mirror looks compared to a glass mirror.  (best analogy I could think of)

Anyway If your not sure what you are looking at, take a solder iron and touch\heat up each and every joint so they just melt and then solidify again. (They should look shiney) This will likely fix your problem.
Do not add additional solder and be careful to not burn the board. Have the board laying flat when you do this.  A 25 watt solder iron should work for you;  one of those big soldering Guns might be overkill.

So you state:  "The price of JTminer is not as high as you think (The price on the website is outdated). " 
Then I say, correct the website. Alternative would be for you to provide legitimate information for pricing here.
Break it out: like,   buy 1 = $xxx   buy 2= $xxxx  buy 5= $xxxxx    buy 10 = $xxxxxxxx .  It really isnt that hard.

Using your own words....  "If you are a serious and reasonable" and (to add on) legitimate seller post substantive information. 
Stop with the riddles, the story telling, the evasive answers, the innuendo.   I have to say that attacking people questioning you does not put you in a good light
nor does it enhance your "TRUST STATUS".

I think you may have missed the boat on sales of your product.   Too bad, because at first I thought you might really have something good here.

Proverbs 11:24
One gives freely, yet grows all the richer; another withholds what he should give, and only suffers want.


2 Peter 2:3
And in their greed they will exploit you with false words. Their condemnation from long ago is not idle, and their destruction is not asleep.

The thread is titled "JingTian"...
Just to clarify; Is it JianTian or is it JingTian?  Wanting to make sure I am referencing the right entity when I pose my question below.
Guessing that it was just typoed in the post or the title....

And now to my question:
Are JointDoctor and jayson001 affiliated in any way with JianTian/JingTian)?

Competition must be tough these days.  Ninja actually ships from Arizona and has them in stock.   

There is plenty of factual information in this forum to justify having doubts as to the veracity of the claims made by skyfromwwell and seeksilence.  If the miner exists and is in production, Price would be too high to enter the market…. Delivery date is still not affirmed… No proof of inventory… legality (IP)…    Lot of storytelling and evasive answers by the miners representatives. I think this miner would be a lost cause.  You fellas just keep your Miners and continue mining bitcoin for yourselves.  It doesn’t really matter if it can be proven this is a legit company or a scam… From a business standpoint, this is not a good deal. 

SeekSilence stated they are waiting for reviews from trusted members.  Checking around, reading different posts, and asking questions (as is my nature), I read some not so reassuring feedback.  As far as I am aware, None of these folks have a miner in hand at this time.

Lets see if you have an answer for this: 
Provide some names of the "trusted members" that actually have a miner in hand; and as you  say, are reviewing and testing your miner.

For all anybody knows; you and skyfromwell (and a few other accounts here) could be one and the same person.

Hope still prevails.  However, Beginning to have serious doubts about you being legit.

SeekSilence, 
I think many of the forum members are curious about your real purpose here too.  Questions have been asked and you have provided some information; but have not been totally forthcoming.... slowly the story comes out. Why are you evasive concerning UJKA’s questions? Provide a legitimate answer concerning the chips.  Be honest and upfront, none of this story time Bullsh**.  You have to understand that Scams are widespread in Bitcoin right now. So, the more open and transparent you are the quicker the skepticism will disperse. This is business; proof is required. Otherwise you could be one of the most honest people in the world and no one will believe you. And because you have not established trust with potential customers, you will not be successful in business. What’s the hang up with providing a miner to someone for validation and verification of what you claim? The longer you wait, the less palatable your miners will be. Price is too high at this juncture and as time passes it will be increasingly MORE DIFFICULT to get ROI for your miner.  So reasonably, consider this; WHY would one invest in your miner (even if it were the best ever made) if they could not make ROI, much less make a profit?  You boys need to get your act together!

Thank you for the clarification SeekSilence.
What are your thoughts on inviting one or two of these forum members to conduct an onsite visit to your production facility in China?

Since you and Skyfromwell  seem to be in business together, it doesn’t make sense that you would not know samples have been sent out...

What’s the chances of a forum member conducting an onsite visit to your production facility in China? Validation and verification... might build trust!
And your prices are too high; There is better bang for the buck with proven miners that are already in production and being shipped.
I imagine your miners are still in the testing and development stage; you have not ramped up production because you are taking pre-orders to
acquire working capital, and you have no standing inventory for immediate shipment.
How will you keep up with orders if you have nothing in inventory to ship?

Have one or two of these forum members conduct an onsite visit to your production facility in China; and you foot the bill.
 

With Sushi, ninjatech.org, and 112bit... that makes three distibutors in US.  Is Bitmain coming out with something new?

Suggest you send a unit to a Trustworthy senior member of the community for testing and validation of your product.
Someone like GreaterNinja would be a good choice. I think a lot of people here would agree that he and his team at Ninjatech
have an establised business reputation for reliability, honesty, and technical proficiency within the community.
He could provide feedback to the community.

I would think the extra cost is for the service and time setting it up; not just the psu, paperclip, and 2 power wires. 
For somone new and not sure what to do, it maight make sense to go that route.

Looks like Ninjatech sells a  "turnkey" system, Full bitcoin kit, on their webpage.
