This is a legally mandated consumer protection right in the EU that gives you a cooling-off period to return your Ledger device for a full refund, even if you have already opened and tested it.
Ledger's sales terms transfer risk of loss or damage to the buyer the moment the device is handed to the shipping carrier, meaning consumers bear responsibility for lost or damaged shipments before they receive their product. The terms also broadly exclude Ledger's liability for any cryptocurrency losses, wallet compromise, or indirect damages resulting from use of the device, which is significant given the high-value assets these wallets protect. You can document your delivery condition with photographs immediately upon receipt and retain all packaging to support any warranty or return claim through Ledger's support portal.
