Return & Refund Policy
RETURN & REFUND POLICY
Thank you for shopping at Stemora. We want customers to understand the return and refund process before making a purchase. This Return & Refund Policy explains eligibility requirements, return procedures, shipping responsibilities, refund processing, damaged or incorrect items, cancellations, and other important conditions.
This policy applies to purchases made directly through https://stemora.us. Returns for products purchased through another seller, marketplace, or website must be requested from the original seller.
Nothing in this policy is intended to exclude or limit any rights or remedies that cannot lawfully be excluded or limited under applicable consumer protection law.
RETURN ELIGIBILITY
Unless otherwise stated on the applicable product page, you may request a return within 30 days after the date the order is recorded as delivered.
To qualify for a return, the product generally must:
- Be unused, unassembled, unmodified, and in substantially the same condition in which it was received
- Include the original packaging, manuals, accessories, components, labels, and other materials supplied with the product
- Show no signs of misuse, contamination, improper installation, unauthorized repair, intentional damage, or excessive handling
- Be accompanied by valid proof of purchase from Stemora
- Be returned according to the written instructions provided by our customer support team
Opening an outer shipping carton solely to inspect the product does not automatically make an item ineligible for return. However, products that have been assembled, programmed, installed, soldered, cut, altered, used in an experiment, exposed to chemicals, or otherwise changed may not qualify as unused returns.
Return eligibility is determined after the returned product has been received and inspected. Approval of a return request or issuance of return instructions does not guarantee that a refund will be approved if the returned product does not satisfy this policy.
RETURN REQUEST DEADLINE
A return request must be submitted within 30 days after delivery. If the request is approved, the product must generally be shipped within 7 days after we provide the return authorization and instructions.
A return may be declined if:
- The request is submitted after the applicable return period
- The product is shipped after the authorization period has expired
- The product does not meet the return conditions stated in this policy
- The package is sent to an unauthorized or incorrect address
- The order was not purchased directly from Stemora
These limitations do not apply where a different remedy or period is required by applicable law.
HOW TO REQUEST A RETURN
Before sending any product, contact us at:
Email: vaioamaonaoak@gmail.com
Please include:
- Your full name
- Your order number
- The email address used to place the order
- The name of the product
- The reason for the return
- Clear photographs or video when the request concerns damage, defects, missing components, an incorrect item, or another condition that requires verification
If the request is eligible, we will provide written return authorization and instructions, including the applicable return destination.
Do not send products to the legal or business correspondence address shown on our website unless our customer support team expressly instructs you in writing to use that address. Our legal address is not automatically our return address.
Returns sent without prior authorization or sent to an incorrect address may be refused, delayed, returned to the sender, or considered ineligible for processing.
RETURN SHIPPING COSTS
If you return a correctly supplied product because you changed your mind, ordered the wrong item, selected an incompatible product, or no longer want the product, you are generally responsible for the return shipping cost.
If we verify that the product was materially damaged during delivery, defective upon arrival, incomplete, or different from the product ordered, Stemora will provide an appropriate remedy and may cover reasonable return shipping costs where applicable.
We do not reimburse premium, expedited, oversized, or unauthorized shipping costs unless we approved the shipping method in writing before the product was sent.
Customers are responsible for securely packaging authorized returns and following the provided shipping instructions. We recommend using a trackable shipping method and retaining the carrier receipt and tracking information until the return has been completed.
Responsibility for a customer-arranged return remains with the customer until the package is delivered to the authorized return destination, except where applicable law provides otherwise.
NON-RETURNABLE PRODUCTS
To the extent permitted by applicable law, the following products may not be eligible for change-of-mind returns:
- Gift cards
- Customized or personalized products
- Products clearly identified as final sale before purchase
- Downloadable or digitally delivered materials after access or delivery
- Consumable or single-use experiment materials that have been opened
- Filament, sealed components, or other materials that have been opened, partially used, cut, contaminated, or improperly stored
- Products that have been assembled, installed, programmed, soldered, modified, or incorporated into another project
- Products damaged through misuse, improper voltage, incorrect wiring, incompatible equipment, unauthorized repair, or failure to follow instructions
- Products missing original components, accessories, packaging, manuals, or identifying labels
- Items that cannot be safely resold because of contamination, chemical exposure, biological exposure, or another health or safety concern
An exclusion for change-of-mind returns does not remove any rights you may have regarding products that arrive defective, damaged, incorrectly supplied, or otherwise covered by applicable law.
COMPATIBILITY AND INCORRECT PURCHASES
Many products sold by Stemora require compatibility with particular microscopes, microcontrollers, robotics platforms, 3D printers, electrical systems, dimensions, voltages, connector types, thread sizes, or other equipment.
Customers should review the product description, measurements, specifications, compatibility information, and required accessories before placing an order. If a correctly described and correctly supplied product is returned because it is incompatible with the customer’s equipment or project, the return will generally be treated as a change-of-mind return.
Contacting us before purchase can help clarify available product information, but customers remain responsible for confirming that a product is suitable for their intended use unless applicable law provides otherwise.
DAMAGED, DEFECTIVE, INCORRECT, OR INCOMPLETE ITEMS
Please inspect your order promptly after delivery. If a product arrives damaged, appears defective, is incomplete, or is different from the product ordered, contact us as soon as reasonably possible, preferably within 7 days after delivery.
Please retain:
- The product
- The original product packaging
- The shipping carton
- Shipping labels
- Manuals and accessories
- Photographs or video showing the issue
Depending on the circumstances, we may request additional information or reasonable troubleshooting steps to determine whether the issue relates to the product, setup, compatibility, installation, power source, or another cause.
After reviewing the available information, we may offer an appropriate remedy, which may include:
- Replacement components
- A replacement product
- A partial refund
- A full refund
- Return instructions for further inspection
The appropriate remedy depends on the nature of the issue, product availability, applicable law, and whether the problem can reasonably be resolved with a replacement component or troubleshooting assistance.
The request to contact us within 7 days helps us investigate shipping and fulfillment issues promptly. It does not eliminate any non-waivable rights available under applicable law.
PRODUCT DAMAGE CAUSED BY USE OR INSTALLATION
A return or refund may be denied when damage results from circumstances including:
- Incorrect assembly or installation
- Use with incompatible equipment
- Incorrect voltage, polarity, wiring, or power supply
- Failure to follow product instructions or safety warnings
- Dropping, impact, moisture, overheating, or improper storage
- Unauthorized modification, soldering, cutting, drilling, repair, or disassembly
- Normal wear and tear
- Use outside the product’s stated educational, hobby, or maker purpose
This section does not apply where the damage resulted from an existing defect for which Stemora is responsible under applicable law.
RETURN PACKAGING
Authorized returns must be packaged carefully to prevent damage during transit. Whenever reasonably possible, use the original product packaging and include all components, accessories, manuals, and protective materials.
Do not place a shipping label directly on retail packaging when an outer shipping box is reasonably available. Products returned with insufficient packaging, missing parts, contamination, or additional damage may receive a reduced refund or be rejected to the extent permitted by applicable law.
Customers should remove batteries from returned products when instructed and package electronic components in a manner appropriate for transit.
Do not return liquids, chemicals, biological materials, used specimens, contaminated tools, damaged batteries, swollen batteries, leaking items, sharp objects without protection, or other potentially hazardous materials unless our customer support team has provided specific written instructions.
RETURN INSPECTION
After the authorized return is delivered, we will inspect the product and notify you whether the refund has been approved, partially approved, or declined.
The inspection may consider:
- The condition of the product
- Whether all components and accessories were returned
- Signs of use, assembly, installation, programming, modification, soldering, or damage
- Whether the returned product matches the original order
- Whether the return was submitted and shipped within the applicable period
- Whether the return instructions were followed
Inspection and processing times may vary depending on the product, return destination, package condition, and volume of requests.
REFUNDS
If a refund is approved, it will generally be issued to the original payment method used for the order. We do not normally issue refunds to a different payment method, person, bank account, or card.
Approved refunds are generally submitted within 5–10 business days after inspection and approval. After we submit the refund, your bank, card issuer, payment provider, or financial institution may require additional time to post the credit to your account.
Stemora does not control external financial institutions’ processing times.
If the original payment method is no longer available, contact us. Any alternative refund method will be considered only where reasonably necessary, legally permitted, and capable of appropriate verification.
PARTIAL OR REDUCED REFUNDS
To the extent permitted by applicable law, a partial or reduced refund may apply when:
- The product is returned with missing accessories, components, manuals, or packaging
- The product has been used, assembled, altered, damaged, or handled beyond what is reasonably necessary for inspection
- The product’s value has been reduced by the customer’s actions
- Unauthorized shipping costs or other non-refundable charges were incurred
- Only part of a multi-item order is returned
We will explain the reason if a refund is reduced following inspection. No reduction will be applied where prohibited by applicable law or where the reduction resulted from a verified defect or error for which Stemora is responsible.
ORIGINAL SHIPPING FEES
Original shipping fees are generally non-refundable for change-of-mind returns or returns caused by incorrect customer selections.
Original standard shipping charges may be refunded when we verify that the return resulted from our fulfillment error, an incorrect product, a materially defective product, or damage occurring before delivery.
Any premium or expedited delivery charge selected by the customer may remain non-refundable except where required by applicable law.
EXCHANGES AND REPLACEMENTS
Stemora does not guarantee direct exchanges for change-of-mind returns. The most reliable option may be to return an eligible product and place a separate order for the preferred item.
For verified damaged, defective, incorrect, or incomplete products, we may provide replacement components or a replacement product where reasonably available.
Replacement availability depends on current inventory. If an appropriate replacement is unavailable, we may offer a partial or full refund as appropriate.
A replacement does not restart or extend the original return period except where required by applicable law or expressly confirmed by us in writing.
ORDER CANCELLATIONS
You may request cancellation by contacting:
Email: vaioamaonaoak@gmail.com
Cancellation requests should be submitted as soon as possible. We will attempt to cancel an order if it has not entered processing, fulfillment, or shipment, but cancellation is not guaranteed.
Orders may begin processing shortly after they are placed. Once fulfillment or shipment has started, we may be unable to stop the order. If cancellation is no longer possible, you may request an eligible return after delivery.
If we successfully cancel an order before shipment, any refund will generally be issued to the original payment method. Payment-provider processing times may apply.
INCORRECT OR INCOMPLETE SHIPPING ADDRESSES
Customers are responsible for entering a complete and accurate delivery address at checkout and reviewing the order confirmation promptly.
If you notice an address error, contact us immediately. We cannot guarantee that an address can be changed after processing has begun.
If a package is returned because of an incorrect or incomplete address, refused delivery, failure to collect the package, or another circumstance attributable to the recipient, we may offer, where reasonably available:
- Reshipment after payment of applicable additional shipping costs
- A refund of the recoverable product amount after deducting non-refundable shipping costs and other amounts permitted by law
No refund or reshipment can be completed until the package has been returned or the relevant circumstances have been reasonably verified.
PACKAGES MARKED AS DELIVERED
If tracking shows that a package was delivered but you cannot locate it:
- Confirm the shipping address on the order
- Check the mailbox, porch, building entrance, reception area, parcel locker, and other safe locations
- Ask household members, neighbors, building staff, or reception personnel whether they accepted the package
- Contact the carrier for delivery details
- Notify Stemora promptly if the package remains missing
A delivered tracking status does not automatically determine the outcome of every claim. We will review the available tracking information, delivery evidence, carrier response, address information, and other relevant circumstances.
We may ask the customer to cooperate with the carrier’s investigation or provide additional documentation where reasonably necessary.
REFUSED AND UNCLAIMED PACKAGES
Refusing a delivery or failing to collect a package does not automatically qualify the order for a full refund.
If the package is returned to an authorized facility, we will review its condition and the circumstances of the return. Original shipping charges, return shipping costs, carrier fees, and other permitted expenses may be deducted from the refund where the return was not caused by Stemora’s error.
Any deductions will be subject to applicable law.
INTERNATIONAL RETURNS
For orders delivered outside the country from which the product was shipped, return shipping costs, customs declarations, duties, taxes, brokerage charges, and import-related expenses may apply.
Unless the return results from a verified error by Stemora or applicable law requires otherwise, customers are responsible for return shipping and related international charges.
Duties, taxes, and customs fees paid directly to government authorities, carriers, or third parties may not be refundable by Stemora. Customers may need to contact the relevant authority or service provider regarding possible reimbursement.
Do not return an international order without receiving written instructions from us.
PROMOTIONAL DISCOUNTS AND BUNDLED PRODUCTS
Refunds for discounted, bundled, or promotional purchases will be calculated based on the amount actually paid and the conditions of the applicable promotion.
If returning part of a bundle causes the remaining products to no longer qualify for a discount, the refund may be adjusted to reflect the price of the retained items, to the extent permitted by applicable law.
Free products included with a purchase may need to be returned if the qualifying order is returned. If the free product is not returned, its stated or reasonable value may be deducted where legally permitted.
CHARGEBACKS AND PAYMENT DISPUTES
We encourage customers to contact us first regarding order or refund concerns so we have an opportunity to review and resolve the issue.
This does not prevent customers from exercising any rights available through their bank, card issuer, payment provider, or applicable law. Customers should not knowingly submit duplicate refund requests or provide inaccurate information in connection with a payment dispute.
If a payment dispute is opened while a refund request is pending, processing may be affected by the payment provider’s procedures.
POLICY CHANGES
We may update this Return & Refund Policy to reflect changes in our products, operations, payment services, shipping procedures, or legal requirements.
The policy that applies to a return will generally be the version in effect when the order was placed, unless a later version provides the customer with more favorable terms or applicable law requires otherwise.
