Bitmain deserves to be nominated for an award.
Unfortunately the award is not a positive one - the level of support this company is providing is a joke.
Product quality of R4 is terrible, so I send my half working antminer for warranty fix one week ago. DHL courier said it was delivered on 18th of Jan. This is the response I have received from the most terrible support company of the year:
Dear Bxxxxxx
Thanks for reaching out to Bitmain! Our offices will be closed from Jan. 21 to Feb. 03 in observance of the Chinese New Year. Logistics will be out of service and all of repair ticket will be delayed during that period. Responses to your inquiries may be delayed as a result.
Because of the delay of package during the Spring Festival, we suggest you return your miner after holiday if there are still one or two hashboards working.
Our working hours are 9am-6pm Beijing time (GMT+8) from Monday to Friday.
We are working hard to respond quickly to every query.
Nobody told me about this when I was sending the package ....
This company is the WORST and this is what awaits you
Well you failed and wasted ½ hashpower if the gear was 1 good board you should have hashed until Feb 4 then shipped it in.
So that is on you.
The fact the board failed is on them.
So you lost about 14 days of hashing at ½ speed say 4th so lets say .02 btc a week x 2 = .04 btc or about 38 usd.
I feel your loss and anger.
I have a machine on order. So to help balance the worlds karma hopfully preventing my machine from crashing like yours did I opened a rental for solo mining.

I spent .01 btc to rent 50th for around 4-5 hours
