The miners look really nice and I would definitely order atleast one of them but the price is really salty! Over 2k for 1TH :-/
I had made a suggestion to bitmain in an earlier post to add crossbars to keep the metal from bending. Each card is pretty heavy which contributes to this.
A suggestion is a crossbar which keeps the cage intact and from bending, which leads to the cards being loosened....ALSO the crossbar can also be used to lock in a center plate or bar that can keep the cards in place...it can even be a strong plexiglass. UNDER the cards on either side of the backplane, some kind of brace can be used to keep the cards from rocking in transit. This could be a permanent thing or just a temporary shipping aspect (which might need to be noted so people remove it after shipping).
The problem really is not bitmain here. BUT they have to take into account that UPS really doesn't care about what is in the box. All the care about is getting it where it needs to be. And it takes a beating along the way. Gotta make it hard for them not to smash up our hardware lol.
Pretty much this video shows how UPS does things https://www.youtube.com/watch?v=2Q6_9A90cUk

Well darn mine got pretty banged up by UPS again.
Even with the bars to keep the blades in place it still arrived messed up.

They need to put foam blocks between the blades preventing them from shifting about.
This will probably be the last time I order these as UPS seems to like playing football with them or something.

Received two B4 units today. I upgraded the MicroSD's with Class 10 units right off the bat and reseated all of the cards. Took a reboot to get all of the chips on line, but they're both 100%.
16gb cards? Where you got the image? Thanks.
I used 8GB cards. I ripped the image off of the cards the machines came with before powering them on the first time.
received two S2 from batch 4
except wrong power cord and need to reseat all boards everything works fine , only face one small issue ( unable to change password via GUI , all tries return Invalid password )
thanks Bitmain

I just received 5 batch 4 S2s yesterday.
They appeared to be well packaged. Before turning them on, I opened the cases to make sure all the boards and connections were firmly in place.
Out of the 5 units, only one had hashing cards that came unseated during shipment, so I had to reseat those. Luckily the boards didn't have any visible damage and work fine. I also had to bend one connector back into place.
All 5 units have been hashing since last night at ~1TH/s without any random reboots or anything.
I wasn't prepared for how heavy these units are, so I can see how they can be easily damaged during shipment if they are dropped even a small distance. Each S2 weights around 40 lbs!

Got my batch 4 yesterday. Just had to re-seat a few boards, but everything else was just like setting up an S1.
It's probably been stated previously, but they ship with rack mounting brackets, rubber feet, and a Chinese power cord.
12 hour average hashrate on eligius is 957 GH/s.
I have 5 boards not showing a temperature reading.

As far as customer response they have been pretty good. Some minor snafus in the order process but they were on their game. They are responsive and they get the job done.
I got my S2 last night and am very happy with it. It runs as advertised.
aside from the cards sslighly unseating (the bars holding them down need reinforcement and to be sitting flush against the cards as well vs a small space inbetween) the overall experience was good. My hardware arrived and I was able to just set it up.
Some feedback for BITMAIN on the case...due to shipping being apparently a football game (and not in your control)...I would recommend reinforcing the cage and bars that hold the cards down with a crossbar (or 2) to reinforce the existing vertical bars on the cage to lock the cards in place. As it is now it leads to the cage itself having no reinforcement and can lead to bending and the cards falling out and causing the shipping issues and RMAs. Perhaps a center crossbar (or two cross bars) that connect the restraining clamps might solve the problem. Its a simple fix and just requires a little bit extra metal without adding much if anything to the cost of the system. And saves a TON of money on RMAs and any other expenses incurred from shipping damage.
In my case the bars bent..(I was able to fix it) due to the cards weight. This is an issue really through with shipping and how they treat the box on the way. But good work overall. I admire the build quality on the hardware regardless.

Bitmain reception at Bitcoin Conference
Bitmain should take care of the last two posts.
They normally should answer.

Is not acceptable for costumers to take the money and time (so other money) loss for an RMA shipping. And no, coupons don't help in these cases.
First of all, let me say that I have been in this situation… The customer "IS" or needs to be responsible for a clear line of communication… Bitmain gave me their account number to do my RMA .. I all so found out that this was not acceptable in the US in order to generate a return label. I promptly emails Bitmain back and gave them a run down on the situation and they generated the return label on their end .. I was out only a 24 hour loss in return time.. The key to this whole mess is "communication" , and don't give up on that very critical key.. What I found is that Bitmain is their to help you IF you help them help you …….. Now you can be bull headed and say that its all on Bitmain but I'm sorry, in this situation if you want to get results you will have to do some of the leg work in the communication department .. I have several S1's and an S2 … I am happy with my product other then the fact that their is a VERY small ROI that I was well aware of Bitmain is by far better then a KNC or BFL in my opinion .. The only thing that was wrong with my S2 was a bad thermal reader on one card, and I can live with that… I do wish Bitmain had a local US parts house, but all in all I'm very happy with their service ..

Right, there should be some escrow service for all the manufacturers.
We are helpless otherwise.
Escrow maybe is too much, just more attention in the customer support part, and also in the case of s2 a more decent packaging to prevent these horror stories

Wish I had one to help, but with guys like atadro buying 6 there weren't many to go around. Being first has its drawbacks, good luck guys, I hope you get it figured out.
You can say that again. Both of my 2 units are totally fubar'd. Unit 1 had the Raspberry Pi board popped out of the bus, and several cards were out of their slots, but even after re-seating it (and checking all connections), I can't get any connection to the unit. The LCD display lights up but there is nothing displayed, and the green light on the LCD never comes on. The ethernet port seems connected to the switch (switch shows active connection), but 192.168.1.99 cannot be accessed at all via SSH or http or even ping. Dead for all intents and purposes as far as I can tell.
Unit 2 was a great example of total lack of QC (or else the unit was put in a washing machine and run through the "shake it up and spin" cycle). Check out the pics below. I haven't even tried to repair, as the bus connections are so bad (and many are loose) that it is impossible to seat all the boards and even if I could seat them, they would be under great strain. I can't believe they shipped something like this and I can't believe that shipping damage would be to blame for this one.

It could be shipping damage, except that the boxes arrived in perfect condition, not a scratch or ding to indicate rough handling.
I guess I will find out soon enough whether bitmaintech stands behind its products or not.
I take back everything good I have ever said about bitmaintech. I would recommend NOT ordering S2 units at all.
I was able to salvage one of the S2's (with Bitmain's express permission, I took good hash boards from each one and was able to get one S2 working properly after about a week of hard work). On April 22, I shipped the non-working, warped, bent, destroyed hash boards (and all other parts including case) back to Bitmaintech as an RMA via UPS and was promised a full refund. Return shipping (with insurance of $1000) cost me $800. Bitmain gave me a shipping number but it was not valid for customer return shipping (I would have had to be an employee to use the number they gave me) so I went out of pocket.
Bitmain then told me they would ship me a new S2 from Batch 4 in lieu of a refund. I don't want another unit so I already sold the replacement unit.
Now, Bitmain has told me that they cannot locate my package in customs. Chinese customs appears to have quarantined my unit. Bitmain says it because China detected a power cord. That sounds fishy to me, but it doesn't matter. I do not have a refund, and I don't have a replacement unit. I am out another $800 for shipping, and the buyer of my replacement S2 is getting anxious so I may have to refund his money (or buy another S2 that I don't need just so he gets what he paid me for).
Bitmain tried to blame me for not asking them for a return shipping label when UPS rejected the shipping number they gave me! However, always trying to be helpful I told them they could give me store credit for the $800 so that I could buy the next-gen Bitmain product when released (NOT S2 LOL). What did they do? They added another couple of $400 coupons to my account. Thanks for nothing. Now I just want cash back for shipping.
And Bitmain? They stopped responding to my emails as of Saturday.
This whole S2 thing really has made me lose a lot of respect for Bitmain, but I was willing to give them another chance. Now, they way they are treating me is not a good indicator of their future. I would strongly recommend avoiding Bitmain for a while to see if they can get their act together again. Sad, but there it is.
Here is my last email just sent:
Bitmain sent me a mangled pile of worthless computer parts over ONE MONTH AGO. In two boxes, two S2 units from Batch 1. I sent you pictures showing how badly damaged BOTH of my S2 packages were. Bitmain KNOWS that the Batch 1 orders were inadequately secured internally. I managed to salvage one of the units (which took over a week of my time, to find undamaged boards from between the two units and then reassemble both units as best I could).
I then sent back the other S2 package at your request, and had to pay over $800 for return shipping and insurance. I marked that these were returns for warranty repaid as you asked. I sent you pictures of the ruined unit. You know that the package is sitting in customs in China, but has not been picked up. It is likely not fixable anyway.
You know all of this.
So why have you not refunded or re-shipped a new Batch 4 unit? What is going on in customs is NOT my problem. The unit you sent was destroyed when it arrived here. I cannot do any more than I have.
I am owed new Batch 4 unit to be shipped as I asked NOW please, and I am also owed $800 in store credit (NOT an S2 coupon I will never use) for shipping and insurance I had to spend because you did not send me a return shipping label (also not my fault). You can figure out what happened to the return later but it is time for you to give me a new unit or full refund.
FYI, I just received the following message from UPS:
Hey Jeff, This is Mario From the UPS Store #4237 Located at Division & Clybourn, simply contacting you to inform that the package in which you shipped Gao Jianping has not been picked up from custom & they can't get in contact with recipient. Your computer server is at risk for being left in china if the the recipient doesn't pick it up by Wednesday 5/14/2014.
Honestly I had the same experience but with a defective S1. I had paid $240 USD to ship it back to them, international shipping is expensive. They took about 3 weeks to go collect the Ant after continuously asking them to collect the miner or just ship out another unit. I was not compensated for the shipping cost that I paid.
When i asked can you please provide store credit after sending a copy of my receipt. I was told "Take it easy, we have to pay shipping too".
After that, I simply accepted the replacement that was sent about 1 month after I sent back the unit to them and marked it off as a loss. You might be better ordering from another seller on this forum that sells dragon but takes PayPAl, at least you have some protection

Received two B4 units today. I upgraded the MicroSD's with Class 10 units right off the bat and reseated all of the cards. Took a reboot to get all of the chips on line, but they're both 100%.
Upon delivery of my B4 unit today, I wanted to;
1) Image the SD card before turning it on
2) Swap out power supply for a Corsair AX1200
Took the screws off the case, took one look inside, LOLWUT ?, maybe sometime this weekend if I have an hour to spare. Decided to get her up and hashing as is for now *shrugs*
