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

Free 14-Day Returns

Tested it, but it’s not a fit?

Return any product within 14 days of delivery if it doesn’t meet your technical or operational needs.

Initiate returns with ease.

Our RMA process is streamlined — just raise a request, follow the packaging guidelines, and we’ll handle the rest.

Refund or restock, your call.

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

30-Day Hardware Replacement

Covered for any early faults.

All equipment includes a 30-day replacement warranty. If something goes wrong, we’ll repair or swap it — fast.

Replacements shipped in 10 days or less.

Once your return is inspected and approved, we dispatch the replacement promptly to keep your operations moving.

RMA protocol keeps it smooth.

Just ensure all accessories and original packaging are intact — we’ll take care of the technical validation.
