Those S4's are fine......really.......nothing to see here......

Hi all,
I am very disgusted with S4 quality. I ordered 10 psc, 6 working fine (not well) 1 miner have a lot of xx in Asic status (more than 60 xx) and 3 PSUs burnt. I am really curious how bitmain will compensate ours losses! I do not recommend S4 for buy.
I enclose pics of burnt PSUs.
Fire extinguishers at the ready people........
They're aware of the problems, this manufacturer makes PSUs for a number of ASIC companies now and they've certainly messed up. I don't recommend anyone opens up a PSU, you never know the discharge times.
