I had two Bitmain S4s being hosted offsite.  Recently, the PSU blew shortly after the 90 day warranty expired.  Apparently that's not uncommon with S4s.  Like others, Bitmain basically said "too bad, so sad" and refused to replace the junk PSU.  They then admitted their supplier only gives a 90 day warranty on their PSU.  In other words, the PSU is junk. 

Buyer beware of Bitmain hardware and services.

I was looking to buy a used S3 as cheap as possible to be able to debug my app with Bitmain junk, I mean, hardware. 

That's no longer the case.  I have no intention of ever spending another penny on Bitmain.

If someone would like to donate an S3 to me, that'd be great.  Otherwise it's quite possible that my app will never again fully support Bitmain junk.

My terms are:

- I don't care how beat up it is, or even if it's fully functional.  As long as it works long enough for me to test with it.
- I will not use it for mining.
- I will not resell it.

Please PM if you're interested in donating.
