This Limited Warranty is provided by Sierro, Inc. and applies to eligible Sierro products purchased by the original end-user from Sierro or an authorized seller and originally delivered to a country or region supported for that sale. It supplements, and does not replace, rights that cannot be excluded under applicable consumer law.
01
Coverage period
The Warranty Period begins on the date the product is delivered to the original end-user purchaser. When reliable delivery records are unavailable, Sierro may use the purchase date shown on valid proof of purchase to determine the start date.
| Product | Standard coverage |
|---|---|
| Sierro 1000 | 5 years from delivery |
| Sierro 2000 | 5 years from delivery |
| Smart Power Hub, charging cables, brackets, stands, and other accessories | 1 year from delivery |
The 2-Yr Extended Warranty - Sierro 1000 applies only to a Sierro 1000. The 2-Yr Extended Warranty - Sierro 2000 applies only to a Sierro 2000. Each eligible plan adds two years of coverage after the corresponding product's standard five-year warranty.
The extended coverage uses the same original coverage start date as the registered product: the delivery date when available, or the purchase date shown on valid proof of purchase when reliable delivery records are unavailable. This provides up to seven years of total coverage from that original start date. Sierro verifies eligible extended coverage against purchase and customer records using the registration email and available order information. Registration does not replace proof of purchase or delivery.

Remedies and limitations
Any repaired or replacement product remains covered for the rest of the original Warranty Period. After coverage expires, paid repair may be available depending on parts availability and applicable service and shipping charges.
To the fullest extent permitted by law, this Limited Warranty states Sierro's obligations for product defects and limits Sierro's liability to the purchase value of the affected product. Sierro is not responsible for indirect, incidental, special, or consequential loss, loss of data, loss of profit, or loss of use, except where such exclusions are prohibited by law.
Nothing in this Limited Warranty excludes liability that cannot legally be excluded, including liability arising from proven gross negligence, intentional misconduct, death, or personal injury where applicable.
