Most people are charged $175+25=$200 for bitmainwarranty repair.
It was satisfactory to me (at the time), but it suggests one of three things:
1. either some part almost always breaks down in a faulty board (50% probability) or
2. they just charge almost everyone the same because it is simpler (30% probability), profitable to them and is acceptable for the majority.
3. maybe (20% probability) it is also because bitmain proper charges them certain $$ for new boards and gives them certain $$ for non-functional ones (but not burned ones).
no question I got a cheaper repair then others.
And from bitmainwarranty I have dealt with them on and off since 2013. So they were better to me then others.
If you look at my thread about warranties you can read all about their treatment to me.
I would rate it 75-80% of what a solid warranty should be.

Now I am mostly mining gpu
and I am having warranty issues with biostar. they have gear since nov 28th with no info which pretty bad.
intel sent me a dead cpu (first ever for an intel in 20 years) in 7 days
Asrock sent me a replacement mobo in 3 weeks
newegg took a psu and a gpu back
seasonic replaced a dead psu
amazon has accepted 3 gpus for return
sapphire was bad they want a receipt with a serial number and when newegg sent me the gear it did not have a serial number
So 7 fast solid responses
1 complete fuck from sapphire---- I will never buy from them again
1 slow response from biostar jury is out.
while 9 bad items seems terrible.
This is for 25 mobos and 100 gpus.
25 psus at least 30 sticks of ram and 25 ssds.
so it is 9 of 210 items since march.
while the s9 is 4 of 28 since june
I think it could be 5 of 28 as I may have a second dead controller.
I would not be mining so much gpu if btc gear was 4 or 5 bad of 100 with good repairs. and long warranties.
