I read every post in this fu---in topic. From the 1st until now. There were a lot of bitching about rma "yep I have to pay 200$ to send back" yep yep. Guys, these are machines manufactured buy humans, always wil be problems. Rma is to solve them. You buy a machine for 7000-10000$ and you bitching on 200$? (And this machine makes money for you)
I know some guys will hate me when a write this, but this is my opininon about mining and asic industry.
Honestly, if a problem happens within 24 hours of arrival then KNC should pickup the return shipping cost since that's shipping a defective item. However, I personally don't really care about the shipping cost. If a part breaks, I want KNC to charge me a BTC or credit card deposit for 3X the value of the card, ship the part the same day no questions asked. If I don't return the part within 7 days or if it works fine when they get it, then they can keep all or part of my deposit.
