PLEASE READ FIRST! Both hashboards are good HOWEVER... because of the nature of bitcoin, there are no refunds.
EVERY 10-14 days one of the hashboards just STOPS.
-I reboot and it works and hashes at 100% for another 2 weeks or so.
-I don't know why it does this. This is has never been overclocked or overheated.
-While it hashes, it hashes perfectly.
-If you want to know why it is priced lower than the others, this is why. There otherwise nothing wrong with it.
