Refund policy

We want you happy with what you bought — and with what you build. Please read this before opening a kit, because DIY products necessarily have different return rules than sealed assembled goods.

Returns, exchanges, and warranty claims all start the same way: send us a note through the contact form and choose Returns & exchanges. Include your order number and what you would like to do. Please wait for our reply before shipping anything back.

Assembled products, including Cortado microphones

If an assembled product arrives unused and in its original packaging, you may request a return or exchange within 30 days of delivery. Return shipping is your responsibility unless we shipped the wrong item or the item arrived defective — in that case we cover it both ways.

Opened, used, modified, or damaged items are not eligible for a refund except as covered by the warranty below.

DIY kits, parts, and upgrades

Unopened kits and sealed parts may be returned or exchanged within 30 days of delivery, less return shipping.

Once a kit has been opened, soldered, assembled, or otherwise used, it cannot be returned for a refund. Kits are sold for you to build, and we cannot resell partially used electronics.

That said, we are not going to leave you with a dead build. If a kit is missing a part, or a component is dead out of the bag, tell us and we will send a replacement part at no charge. If you are stuck mid-build, that is what Support and the builder forums are for.

Exchanges

Yes, we handle exchanges. If you ordered the wrong variant, want to swap for a different product, or need a different configuration, ask and we will set it up.

1. Open the contact form and choose Returns & exchanges.
2. Tell us your order number, the item you have, and the item you want instead.
3. We will confirm availability, sort out any price difference either direction, and send return instructions.

The same 30-day and unopened-kit rules apply to exchanges as to refunds.

How to start a return

1. Open the contact form and choose Returns & exchanges. Include your order number and what you want to return.
2. Wait for our return authorization and shipping instructions. Packages sent back without authorization can go astray.
3. Pack the item securely and put your order number on a note inside the box.

Refunds go back to the original payment method after we receive and inspect the return, usually within 5–10 business days.

Warranty against manufacturing defects

Zeppelin Design Labs warrants its products against defects in materials and workmanship under normal use for one (1) year from the date of purchase, unless a product page states a different term.

• Covered: manufacturing defects in assembled products, and kit components that fail under normal use.
• Not covered: misuse, improper assembly, incorrect power supply, modification, water or fire damage, normal wear, and shipping damage after you have accepted the package — see our shipping policy for transit claims.
• DIY kits: the warranty covers components as shipped. It does not cover assembly mistakes, cold solder joints, or damage caused while building. We will still gladly help you troubleshoot.

To open a claim, use the contact form and choose Warranty & repair. Send your order number, a description of the fault, and photos or a short video if they help. We may repair, replace, or refund at our discretion.

Order cancellations

If your order has not shipped yet, tell us and we will cancel and refund it. Once it has shipped, use the return process above.
