It is sad that you had trouble with your S1's, and frustration when you tried to get it repaired.
I have quite a few antminer S1's and have never had the problem that you experienced. Maybe you should check the voltage of the power supply that you used with the Antminer that 'blew up', it could be outside the specified range. It is possible that what caused your problem is external to the Antminer, such as the PSU. Do you use any UPS/Surge protection on the AC inputs to your power supplies? Do you have issues with unstable mains voltage or lightning?
Cheers

i have buy two ant s1 at 5.26 from bitmain about 1210￥*2 （about 200$ *2)
and i receive at 6.3，
but both of them have a big problem！
they are all go down to 90-150g in 24 hours
i have try everything such as change 1000w psu,add some fans to reduce the temp to 45 degrees but not work at all。
so i send one of them(s1 goto 90g) back to bitmain at 6.10。
bitmain repair and send back to me quickly at 6.11。
they change me a seem secondhand ant obviously used。date of manufacture is 2013.12 !
and it boommmm ！！！when i connect the psu and open it
in the other side of antminers1 ,fragments and flame blowout to another ants .
it s very danger to me if it booms in the side face to me
and the 500w psu i connect to the boom ant s1 is fine after that，and i have use it to another ant
and i send back to bitmain again but bitmain（范XX one of bitmain boss that you can see in bitmain s web site）
but they hameless to Reply me
1 add 400￥ to repair
2 "help" me to repair ，but not ensure the speed and Stability
。
i had make representation for some days but the just want money and sent back ant miner
recklessly
The results is i have got a Damage antminer s1 at 157g at 6.25 and start to mine.
