Update on 2014-12-02:

Compensation scheme for previous buyers&customers:

Due to a lot of problems (factory`s faults + bugs of controllers + delivery damages) ,we have received so far a lot of user feedback, focusing on saying that our miners are in unstable working conditions/cannot start hashing at all,or even got burned.

We apologize here again for all inconvenience we possibly brought to you.

We are solving the problems by changing factories,strengthening the tests,debugging our firmware ..etc ,at the moment,things are going well,our new batch of Prisma are under test and working well so far.

The compensation scheme for all previous benefit-lost-buyers caused by quality problems of our Prisma miners is the following:

1. All problem products such as hashing boards,controllers, fans, data wires are changable. Please mail them to this address:

ADD：UNIT 10-11,20/F.,RICKY CENTRE,36 CHONG YIP STREET,KWUN TONG,KOWLOON,HONG KONG.
TEL：00852-35688889
Contacts：MISS LI

(We will surely cover the shipping fees but please help disassembling the heat sinks, which is the most heavy and expensive part for shipping,and keep them with you.)

2. A sum of compensation fee will be given to all broken miners buyers. Calculation method follows: (Theoretical daily income with your broken boards of Prisma`s hashrate - actual daily income with real hashrate) * Number of days between the date you received your old Prismas to the date you will have received replaced boards again. Each prisma board is calculated as 287W and 350GH/s. The electricity fee is calculated as 0.1$/KWH.

BTW：We will account your compensation fee with a calculater such as this one: http://www.iasicminer.com/index.php/action-channel-name-counteren

We will check the real hashrate of your broken Prisma boards shipped back.

We can only do it after you receiving your new boards because we can not know your receiving day in advance.

You can get your compensation fee by email us to sale@bitquan.com with the following information and format:

* Personal info,shipping address,tel number
* Date of buying our Prisma
* Your previous individual/exclusive btc payment address
* Number of broken Prsima boards (have to be fit well with the number you shipped back)
* Date you received your miners,date of shipping back
* The picture of the shipping label with the shipping price on it
* Your btc receivable address (it will be best to be the one you paid to us before)

If you bought from resellers, please do this with them directly.
If you were our big buyers (100+ sets order) or resellers,and your broken boards are more than 20 boards per 400 boards,please contact us through email directly.‍

I assume they mean TUBES?? what is the comp. for TUBES?

This is less then optimal, but something is better than 800GH/s of useless hardware.
