After-Sales Care

After-Sales

No empty words. Every promise comes with proof.

Response-Time Commitment

We respond as soon as feedback arrives; handling times and delay penalties are written into the contract for you to review line by line before signing.

A dedicated line for urgent breakdowns. Our promises do not live on a wall — they live in the contract.

Quality Issues Solved First

If a quality dispute arises, your purchase record is all it takes to start a replacement — we solve the problem first, assign blame later.

No burden of proof on you, no hiding behind inspection procedures. If it's our fault, we own it on the spot.

Real Customer References

Customer cases are published with authorization and updated over time — real, verifiable, quotable.

Reputation is not something you claim. Ask us for reference cases and verify them yourself.

Transparent Warranty Terms

Warranty duration and coverage are written into the contract terms, reviewable line by line before signing.

Warranty scope, exclusions and the claims process are all public. Sign or not — read them first.
