*** UPDATE - after weeks of threatening to sue them they finally agreed to replace the boards ******
anyway you can still read my rants showing hw annoying they where to deal with...
Hi.
I bought 2 of Bitmain's Antminer S9's - the 2nd batch. 12.93 GH/s
I plugged both of them in at the same time - in the same room.
They both started up and seemed to be running ok for a few hours.
The temperatures were around 65 degrees C.
Then I noticed that on one of the S9's, one of the hashingboards was reading 0 GH/s
So i restarted it - and then the board was no longer listed on the Status Page.
This was day 1 - within a few hours of being plugged in.
Now bear in mind that I have also had 5, Antminer S7's also running in the same room + the other S9 - ALL WORKING PERFECTLY.
No heat problem, no electrical problem.
Ok, so I tell Bitmain what happened and they tell me to send back the hashing board - then I get this response:

EXCUSE ME?
So I just paid $1800 USD for a broken machine and you tell me that "because it's repairable" that is somehow my fault?!
Are you F**king kidding me?
Then they refer me to the warranty:
"3. In some cases, the warranty will be void, but Bitmain can still do repairs at your own expense if requested. The following events will void the warranty:
a. Customer removes/replaces any components by himself without receiving permission from Bitmain first;
b. Damage caused by poor power supply, lightning or voltage surges;
c. Burnt parts on hash boards or chips;
d. Miner/boards/components damage due to water immersion or corrosion due to wet environment."
Ok, let's see..
(a) does not apply - they told me to remove the hashing board and send it to them'
(b) does not apply - I have 5 other Antminers all running on the same power supply - same room - same temperatures. THEY ALL WORK.
(c) I didn't see any sign of burining on the board - if there is I assume it's because there is something wrong with it.
(d) does not apply
So basically they are trying to screw me.
I am probably going to have to sure them, luckily I have a very good lawyer in Hong Kong. So I will let you know what happens.
But anyway - I personally WILL NEVER BUY ANYTHING from these con artists ever again and I seriously WARN anyone against giving these people any of your money - as they are not willing to replace faulty goods.
My Antminer S9 was faulty within a few hours of starting up.
How any serious business can pretend that that doesn't fall under warranty is beyond my comprehension - only a total asshole thieving lying scumbag would refuse a repair in such a situation.
So BITMAIN you can go and F**K YOURSELF. GOODBYE.
