Manufacturer warranty and Dawin support
No voluntary supplier warranty is included with this offer.BITMAIN’s direct L11 product terms describe a 180-day warranty starting from BITMAIN’s shipping date, limited to the original purchaser buying directly from BITMAIN. Those terms state that warranty responsibility passes to the reseller on resale.
This is general manufacturer information, not confirmation of cover for the supplied reseller unit. Its manufacturer eligibility, shipment history, remaining cover, South African claim arrangements and freight responsibilities have not been verified. No fresh manufacturer warranty period from Dawin’s sale, shipment or delivery is promised. Unverified manufacturer coverage does not mean confirmed absence of manufacturer coverage.
Any separately confirmed manufacturer cover will be disclosed before purchase, including its provider, remaining duration, scope, claim and repair arrangements and freight responsibilities. Dawin does not include an additional voluntary commercial miner warranty. Earlier agreed rights remain unaffected. Read our Miner Warranty and Repair Information. Contact dave@dcmining.co.za for support.
