RMA no way got it from ebay for 15usd
dont know how old it is is it under warranty or anything .
For mining btc it is not good but i am mining altcoins with sha256.
Where can i see is it under warranty ? And sending it to usa from germany is it worth it.
Shipping to the US alone would be at least $30. They pay for return shipping but others have reported getting hit with taxes again.
Either get another one on eBay or just stop looking at it. I had a single with 6% hardware errors last June and I didn't bother with RMA since I would have lost more then the unit was worth.
