Return & Warranty Policy

Refund, Return & Warranty Policy

Last updated: September 2026

At DaierPro, we want you to have a smooth and reliable shopping experience.

This Refund, Return & Warranty Policy explains the conditions and procedures for returns, refunds, exchanges, and warranty claims for products purchased directly from the official DaierPro website.

Our goal is to resolve product issues fairly, transparently, and efficiently.

This policy applies to purchases made directly through the official DaierPro website and, where applicable, authorized DaierPro sales channels.

1. 90-Day Return Guarantee

Customers may request a return or exchange for eligible products within 90 days from the date the order is delivered, based on the delivery confirmation provided by the shipping carrier.

To request a return or exchange, please contact our customer service team before sending the product back.

Please provide:

Order number
Product name
Photos of the product
Reason for the return
Any other information relevant to your request

Once the returned product arrives at our designated return facility and passes inspection, we will process the applicable refund or exchange.

Important

The 90-day return guarantee applies to eligible products that meet the return requirements below.

Nothing in this policy limits any mandatory consumer rights or remedies that apply under the laws of your country or region.

2. Return Requirements

To qualify for a standard, non-defective return, the product should:

Be unused
Be uninstalled
Remain in its original condition
Not have been modified or altered
Include all original accessories and components
Include the original packaging where reasonably possible
Be accompanied by valid order or purchase information

For electrical products, products that have been installed, wired, powered, modified, or otherwise used may not qualify for a standard change-of-mind return, particularly where installation or use has affected the condition of the product.

Returns that do not meet these requirements may be subject to a partial refund or may be rejected, to the extent permitted by applicable law.

Additional Notes

For non-quality-related returns:

The customer is generally responsible for return shipping costs
Original shipping charges are generally non-refundable
Products must be returned using the return instructions provided by DaierPro
Return packages sent without prior authorization may be refused

Please do not send a product back before receiving return instructions from our customer service team.

3. Incorrect, Damaged, or Defective Products

If you receive:

The wrong product
A damaged product
A missing component
A defective product
A product that does not function as described

please contact us as soon as possible after delivery.

For the fastest resolution, please provide:

Order number

Photos or videos showing the problem
A description of the issue

After reviewing the information, DaierPro may provide an appropriate solution, which may include:

Replacement

Refund

The specific solution will depend on the nature of the issue and applicable consumer protection laws.

4. Electrical Product Installation

Because many DaierPro products are electrical components, proper installation is important.

Customers should verify the product's specifications and compatibility before installation, including:

Voltage
Current rating
Load requirements
Terminal configuration
Wiring requirements
Fuse and circuit protection
Physical dimensions
Intended application

Where appropriate, installation should be performed by a qualified professional.

A product may not be considered defective where the problem is caused by:

Incorrect wiring
Reverse polarity
Incorrect voltage
Excessive current
Overloading
Short circuits
Improper grounding
Incorrect installation
Improper use
Unauthorized modification
Use outside the stated specifications

This does not affect any consumer rights that cannot legally be excluded.

5. Refund Process

Approved returned products are generally inspected within 7 business days after arriving at our designated return facility.

After the inspection is completed, we will notify you of the result and arrange the applicable refund or replacement.

Refunds

Approved refunds will normally be issued to the original payment method.

After the refund is issued, the time required for the funds to appear in your account depends on your bank, card issuer, or payment provider.

In most cases, refunds may take approximately 5–10 business days after being issued.

Processing times may be longer during:

Public holidays
Peak sales periods
High volumes of return requests
Payment-provider delays
Other circumstances beyond our reasonable control

6. Exchanges

Product exchanges are subject to inventory availability.

If the requested replacement product is unavailable, DaierPro may offer:

A refund
A replacement with an equivalent product, where appropriate
Another mutually agreed solution

Replacement products may have different packaging or minor cosmetic differences from the original product.

7. Warranty for Quality-Related Issues

DaierPro provides warranty support for eligible products purchased directly from DaierPro, subject to the applicable warranty period and product-specific warranty terms.

Warranty coverage applies to defects in materials or workmanship under normal and intended use.

Where a product is confirmed to have a manufacturing defect, DaierPro may provide:

Troubleshooting assistance
Replacement parts
Product replacement
Repair assistance
Refund, where appropriate

The specific remedy depends on the product, availability, nature of the defect, and applicable law.

8. Warranty Claim Process

To submit a warranty claim, customers may be asked to provide:

Order number or proof of purchase
Product name or model
Photos or videos showing the issue
Description of the problem
Troubleshooting information
Product serial number, if applicable
Installation or usage information

In some cases, DaierPro may request that the product be returned for inspection before determining the final warranty resolution.

Please do not return a product before receiving return instructions from DaierPro.

9. Proof of Purchase

Valid proof of purchase may include:

DaierPro order number
Order confirmation email

Before shipping the return, please:

Contact DaierPro customer service
Obtain return authorization and instructions
Package the product securely
Use a trackable shipping service where possible
Provide the tracking number to DaierPro

Customers remain responsible for the return shipment until it is received by the designated return facility, except where applicable law provides otherwise or where DaierPro has arranged the return shipment.

DaierPro is not responsible for personal items accidentally included in a return package.

13. Refund Exclusions

Unless required by applicable law, refunds generally do not include:

Original shipping charges
Return shipping costs for non-quality-related returns
Customs duties or fees generated by customer-initiated returns
Additional costs caused by incorrect return procedures
Costs associated with unauthorized returns

Any applicable refund deductions will be communicated to the customer before the refund is processed where reasonably possible.

14. Products Damaged During Installation

Electrical products that have been installed or connected to an electrical system may be inspected before a warranty determination is made.

Damage resulting from installation or electrical conditions outside the product's specifications may not qualify as a manufacturing defect.

Examples include:

Connecting a 12V product to an incompatible voltage
Exceeding the rated current
Incorrect terminal connections
Reverse polarity
Incorrect wiring
Short circuits
Improper fuse selection
Improper grounding
Modification of the product housing or internal components

Customers should carefully review the product specifications before installation.

Please do not send products to an address obtained from an old order, invoice, or other source without contacting DaierPro first.

Return instructions and the applicable return address will be provided by our customer service team.

DaierPro may be unable to process unauthorized returns promptly.

16. Consumer Rights

This policy is intended to provide a clear commercial return and warranty process.

It does not exclude, restrict, or replace any statutory rights, warranties, guarantees, or remedies that cannot legally be excluded or limited under the laws applicable to your purchase.

Where applicable law provides greater consumer protection than this policy, the applicable law will prevail.
