Regarding warranty, we haven't mentioned it and (quite surprisingly) no one has asked about it. The warranty period will be 90 days from the date of delivery.
I think 90 days are not enough to obey EU laws for planned EU:EU sales process.
Indeed Europe has a minimum of 2 years
I know there are issues in the United States with 90 day warranties too, one of the main reason you couldnt order Mining Cards from distributors and major brands/stores.
