Returns and Warranty Policy
RESONIKS (SUPPLYZ B.V.) · Version 1.0, September 2026
This policy applies to orders placed through the RESONIKS website. It forms part of, and is governed by, the RESONIKS General Terms and Conditions (the “Terms”). Where this policy is more favourable to you than the Terms, this policy applies; in all other respects the Terms prevail. Capitalised terms have the meaning given in the Terms.
1. We sell to businesses only
RESONIKS contracts with businesses, not consumers (Article 2 of the Terms). The statutory consumer right of withdrawal does not apply to your order. We may ask for a VAT identification number before accepting an order.
The 30-day return right below is a voluntary commercial policy that we grant under Article B6 of the Terms (“Optional return right”). It is not a statutory right, and it does not affect any right you have under mandatory Dutch law.
2. What this policy covers
It covers orders placed through our website that can be shipped as a normal parcel, such as Development Kits, individual MPK801 microphones, ARK141 hubs, adapters and cables.
It does not cover:
QCFlex systems, robots, custom arrays, enclosures and anything else that cannot be sent by normal postal or parcel service;
products that are customised, configured or manufactured to your specification;
systems that have been installed;
Services already performed, including feasibility studies, pilots, training and engineering time;
rented or leased Systems, which are returned under Part C of the Terms;
orders placed under a reseller, distribution or partner agreement, which are governed by that agreement.
For anything not covered by this policy, contact us first and we will agree the route in writing. Please do not ship anything back without that agreement.
3. Changed your mind: 30-day return
You may return a product within 30 days of delivery, provided you give us written notice within that same 30-day period.
Conditions:
the product has been tested or evaluated only, and has not been put into production or other commercial use;
it is undamaged, clean, complete and in resaleable condition, in its original packaging, including the calibration certificate, cables, adapters and all accessories;
you obtain a Return Authorisation (RMA) number from us before shipping;
the return is made at your own cost and risk, so we recommend insured, tracked carriage;
any software licence supplied with the product ends on return and you stop using the software.
Testing means bench evaluation and trial measurements. It does not include installation in a production line, use in ongoing quality control, or any commercial use of the results. We may refuse a return, or reduce the refund, where the product shows wear, installation marks, modification or damage.
We refund the price paid, less any reduction in value. Reduction in value covers missing accessories or a missing calibration certificate, and the cost of any inspection, retesting or recalibration needed to return the product to saleable condition. Shipping costs originally paid are not refunded.
We issue a credit note for the refunded amount. Where the invoice is still unpaid, we credit the invoice instead of making a payment. Otherwise we refund to the original payment method within 14 days of receiving and inspecting the product, or, where a refund to that method is no longer possible, by bank transfer to an account you nominate.
4. Damaged in transit, or wrong or missing items
Please inspect your delivery on arrival. Report visible transport damage, a wrong item or a missing item in writing within 5 business days of delivery, which is the acceptance window in Article 4 of the Terms. Where possible include photographs of the packaging and the product.
If the damage or error is ours or the carrier’s, we replace the item or refund it, and we pay the return and replacement shipping. Keep the original packaging until we confirm the next step, as the carrier may need to inspect it.
5. Faulty product: 12-month warranty
Separately from the 30-day return right, we warrant that on delivery the product conforms to its specification for 12 months (Article B4 of the Terms). If a product is faulty within that period we will, at our option, repair or replace it.
Notify us in writing within 30 days of discovering the fault (Article 13 of the Terms), describing the fault and, where possible, how it can be reproduced.
Obtain an RMA number before returning anything.
For warranty returns, you pay the cost of sending the product to us and we pay the cost of returning the repaired or replaced product to you.
A product found to be faulty on first use and reported within 30 days of delivery is treated as dead on arrival: we replace it promptly and cover the freight both ways.
The warranty does not cover normal wear, misuse, unauthorised modification, faulty calibration or adjustment by you, or unsuitable site conditions. For third-party devices, the manufacturer’s own warranty applies.
6. How to tell us
Email support@resoniks.com with the subject line “Return request - [your order number]” and include:
your order number and the invoice or order date;
the product and, where applicable, the serial number;
the quantity;
which route you are using: 30-day return, transport damage or wrong item, or warranty claim;
a short description of the reason, with photographs for damage;
whether you want a repair, a replacement or a refund.
We reply with an RMA number and return instructions within 3-5 business days. Returns received without an RMA number may be refused or delayed.
7. Where to send returns
Once you have an RMA number, send the product to:
RESONIKS (SUPPLYZ B.V.)
Van Lumeystraat 55
2581 XB Den Haag
The Netherlands
Please pack the product so that it is protected in transit, in its original packaging where possible. Risk of loss or damage in transit stays with you until we receive the product, except for transport damage and warranty returns handled under sections 4 and 5.
8. Returns from outside the EU
If you return a product from outside the European Union, declare it to customs as returned goods. Declare a realistic value for customs purposes; do not declare a return as a gift or at nil value, as this causes the parcel to be taxed or held. You are responsible for export formalities and for any duties or import charges arising on the return. We cannot refund import duties, customs charges or import VAT you paid on the original delivery.
9. Questions
Email support@resoniks.com or call +31 85 064 4433. This policy is governed by Dutch law, and disputes are subject to Article 17 of the Terms.
10. Relationship to our Terms and Conditions
This policy supplements our General Terms and Conditions and does not replace them. Anything not addressed here is governed by the Terms. In the event of any doubt, conflict or inconsistency, the Terms prevail, except where this policy expressly grants you more than the Terms require, in which case this policy applies to that extent. We may update this policy; the version published at the time you place your order applies to that order.
