Dear subscriber,
We are writing to inform you that we have received reports that some fraudulent sellers or scammers are trying to sell next-generation models of Bitmain’s Antminers, such as Antminer S10 or S11, none of which exist yet. The latest Bitcoin or Bitcoin Cash miner from Bitmain continues to be the Antminer S9, which can be purchased on www.bitmain.com
We sell miners only on www.bitmain.com We do not have any physical location, in China or abroad, where you can purchase Bitmain’s miners. There is no other way to purchase Bitmain's products from us.
If the option to buy a product that is listed on the website is not there, the product is sold out and there will likely be another batch of that product soon.
If we know the date or time for the next batch releases of any product, we announce it on our Facebook page (facebook.com/Bitmain) or Twitter account (twitter.com/Bitmaintech).
The price of a batch is usually only available when the batch is released.
We wish you all a happy mining experience with Bitmain’s products.
Regards,
The Bitmain team


@ op please write scam in your title.

As for :
S-9
T-1
avalon 841

all three have issues.

but  I did decide to keep the 5x T1's sent to me for testing/demo.
I like -ck's firmware updates  and don't mind the pool limitations.

My avalon comes today  I will see how cool I can keep it.
It appears that I won't be able to have a lot of them as 30c or 86f is not possible to do in the main solar array loft during the summer.

and s-9's break a lot.
