Our best-in-class warranties

3-Year Extended Warranty

Extended protection, enterprise-grade.

All enterprise hardware is backed by a 3-year warranty — triple the industry standard — covering defects under normal use.

Professional repairs & replacements.

If a hardware issue is confirmed, we’ll repair or replace the unit. Replacement parts carry either original or 3-month coverage.

RMA process, simplified.

Once an RMA is approved, return the defective unit within 10 days. We handle the rest — no service gaps.

Service Boundaries & Exclusions

What’s covered — and what’s best avoided.

Your warranty covers defects under normal use. For continued protection, avoid accidental damage, unauthorized repairs, third-party parts, or extreme environments.

Know your location’s service type.

In some regions, return-to-factory or remote service may apply. On-site service depends on infrastructure availability.

Minimal documentation required.

To initiate service, just submit the invoice and warranty card — no red tape, no waiting.

14-Day Money Back Guarantee

Changed your mind? Get a refund (restocking fees may apply) or swap with another product.
