These look like the AMT miners with red PCBs. Additionally considering the terms and agreements outlines, why would anyone want to buy from you? Also its patently obvious you are using f2pool to mine with this hardware. So already off to a bad start.

1 ) Once sold, no refund no return. Why not? If the product is defective or does not work as advertised this basically frees you of responsibility. No thanks
3 ) One month after receipt to pay maintenance , freight paid by the buyer. So we are on the hook to pay for your design defects? the most common issue I see happening here is failure of the PSU based on the specs posted. 1080w usage on an 1100w PSU is just screaming for failure as most PSUs cannot sustain that amount of strain on a 24/7 basis. 80 percent efficiency label is there for a reason and the ones being put into these units likely are not even rated well. Might want to state what brand you are putting in there for accuracy. People should know what they are getting. What ASIC chip is being used?

So again why would we want to buy this when bitmain and spondoolies have much better offerings with better guarantees on the hardware?

Sir，

if the miner cant work at the beginning , we can reship.
if you think other's miner is better, you can ! we respect clent's chioce.
and thank you for all those question, we will take a think about it and do better.

There are other similar companies like yours, with better attitude and want to take customer money
If your attitude is like this,  better mine for your self you will avoid retail customer hassle...
 

Geez! Don't they have 1200-1300w PSUs anywhere in China?
