I asked to buy bitmain 2 blades, was paying them because my miners have five months, and are out of warranty, but bitmain told me that no longer produce pcb S5, and I had to look on amazon or ebay.
a response of shit,

And I repeat to say, chips are built with poor material, that's why they are cheap.

Now I bought a used PCB, from Tupsu, a user of the forum here, I'm waiting for is that I get.

This happens because the chips are built with poor materials, which is why we have many errors, and many burned pcb

so you're telling me that after 3 months, you break a pcb, after one week break the other, I can throw the miner without being able to buy spare parts? by boys it is absurd.

bitmain could do so: give 6 months warranty and 90 days,
for spare parts after expiry of the 180-day warranty I must be borne by the buyer,
spare parts will only be available for 365 days.

so a user knows that the expiry of 180 days, regardless of its miners work or not, may decide to buy a pair of PCB and set aside in case it fails.

so does a good company, not as bitmain ago, many of us are working with one single PCB, or miner put aside because all 2 pcb burned, and you can not even replace them.

bitmain has a wrong policy.

2 are the things, I put towards more days of warranty and spare parts to the customer,
or it begins to use good material, and not bad material, because what use is bitmain bad material.
we want to see how many of us have burned pcb that do not work?

philipma thanks to this I added 180 days
If people vote the final result will be sent directly to bitmain.

batch 2   4,66 th/s

batch 3   4,86 th/s


what is the difference?

rate of hardware failures? same materials, same amount of chips,? assembled by the same people? but what you're saying?You tell me how do you to realize if they send you after you buy 2 batch 3 batch? that the difference are 20 gh / s?



PS:  do not worry about the thread, you can quit at any time

open voting

please vote for more people as possible thanks

could also compensate with free shipping because wants to be an honest,
but the thing I hate are the 3 months warranty, when it should be 365 days, and not 90 days, and then to allow people not to throw way the miner when you burn the hashboard not be able to buy spare parts.

I repeat, most people pay in bitcoin bitcoin, = is evading taxes in China, so it is all gain for them, if you see the price of each car, paid in BTC has a value, if you pay in usd it has a price top, okay? so if I pay in btc no one knows that I'm buying, so it can not declare the goods available for sale, or that costs s7 1680 could declare $ 350, and arrived in Italy would pay only 80 euro (about $ 91) instead of 325 € (about $ 392).
bitmain and China, and as all Chinese around the world evade taxes and send money in China, the sequester all the toxic material, and bad material, so do not tell me that wants to be legal bitmain,. when there is no money, no one is legal.

I do not want the pcb free, I'll pay the pcb and transport,.
a miner can not last five months with 350 frequency, and burning,
My psu 1200w and platinum
220V power in Italy.
I do not think there's anything wrong.
Customers who buy should be able to buy spare parts, because you can not throw away, once burned. obviously as we see the materials it uses bitmain are poor.

1) listen, products making Bitmain are shit, I can guarantee 100% of all products manufactured in China are cheap,
2) no one gives you 3 months warranty, does not exist, must have a minimum one year warranty.
3) certainly it enriches people for fools like you who are not aware of buying poor quality materials.

after I spent $ 2,000 five months ago, now I find myself with 2 blades burned and I can not use the miner.
my psu are evga 1200 platinum,
my frequency and factory 350M.

and I repeat that it is the public like you that makes rich people like bitmain.
I hope to esere been clear.

example: if you buy a car and five months after breaking the radiator, but do not manufacture more radiators for that machine, you do force pundit, since you're defending bitmain selling bad material. and I say.

Bitmain is smart, get paid in bitcoin does not cost any fee to him, but when ships in the world says the price in full,. very clever, if this is to respect the customers who buy products from him, we are in deep shit,. could save customs duties for its customers, instead does nothing. always think to get rich,

I think that their psu 1600w, is of poor quality, as the miner who produce, which is why only give 90 days warranty for the miner, and 365 to the power supply.

I will make a proposal to bitmain, to save the people who live in the European community, so as not to pay so much money for the customs duty

but we pay in bitcoin, so he has a duty to save us both on the expedition, which on customs duties.

another thing, I do not agree on the guarantee, 90 days are very short, the guarantee must be at least 365 days.

current price usd for Antminer S7  $ 1658 = Euro 1479 ( price euro for 1 Antminer S7 )  + 22% ( Italia ) = 325 euro . Total price for 1 miner = 1800 euro + shipping = 48 euro.

total price for buy 1 antminer S7 = 1848 euro  (usd = 2071,6072  )

 


because when Bitmain sends you declare the real price?
just declare $ 150 per miner

customs fee 29 euro   ( usd  25,8698 )

I wanted to open this post to understand the duties of the various countries when we order goods from bitmain.

guys try to be objective in things, we all know that Chinese products are of poor quality, then we should not be surprised of the problems we encounter when we buy in China, you do not just mean the world of the miners, but all over. no offense to the Chinese.
