We do have a factory warranty with all miners. Bitmain offers a 180 day warranty on miners from the shipdate. We offer a Supplementary Service Plan which covers labor & repairs, but does not cover parts, however we do house all parts for repairs, so there is no wait time for ordering and shipping. The cost for a 1-2 year plan is 5% of the value of the hardware, and the 3 year plan is 7% of the value of the hardware. If you don't purchase the plan, you are responsible for the costs of part and labor to repair the miner.

Please let me know if you have any other questions.
