Bitcoin Miner is a Specialty Item at the moment. (Fortunately or Unfortunately)
Bitcoin Mining Hardware, the life span can be very short.
At least Bitmain Hardware sold directly from Bitmaintech.com is sold from Hong Kong, SAR, China. A special district within China.
You can certainly buy from some resellers in EU. Some of the person resells Antminer even post comments here time to time for Antminer products and also provide technical assistance. They may be held on the EU standard but not when you buy direct from the Hong Kong Company.
Direct Sale only covers the original buyer for the 90-day warranty.
Bitmain is strive to make better and long lasting hardware every day, however, bitcoin mining hardware is still a very early stage mathmatical system that is specially build for a small nitch of market by special demand.
Please be patient with us and we will try to remain the best in Warranty when it comes to the industry standard.
