100% Satisfaction Warranty Policy

We offer complimentary 30-day returns if you’re not satisfied with your purchase for any reason. All of our products also come with a standard 1-Year Limited Hardware Warranty.

Note: The warranty is provided in addition to the rights and remedies granted to you by seller or granted to you under applicable legislation. Therefore, any remedy (e.g. rectification, claim for damages, right to terminate the contract) granted by Sum LLC or by the law applicable remain unaffected e.g., the right to claim lack of conformity within 12 months from the date of purchase.

The warranty covers all defects compared to the specification of the product in question, that may arise in the product within the below-mentioned warranty period, however, with the exceptions set out below:

  • Unless otherwise explicitly stated in documents provided in connection with the purchase, the warranty period is twelve (12) months.

  • The warranty period starts when the product(s) is delivered to the first end-user. This warranty does not extend to any product whose serial number has been defaced or altered, just as the warranty will cease if you make modifications in the software not authorized by Keytron.

  • The following are NOT covered by the warranty:

- Accessories and spare parts (including but not limited to cables, carrying case etc.) sold separately i.e. not bundled with a Sum LLC product.

- Defects that have been caused by wrongful use, incorrect installation, incorrect repairs/modifications, or maladjustment of the product, or neglect.

- Defects that have been caused by lightning, fire, water, or other events of force majeure.

- Defects in consumables, (i.e. components that are expected to require regular replacement including without limitation: carrying case, cables etc.) or use beyond the expected lifetime of the consumable in question.

With the herein stated exceptions to claim under the warranty, you may contact info@sum-products.com if a defect covered by the warranty arises in your product within the warranty period. Sum LLC will rectify the defect by, at our choice, either repairing the defective product or replacing it with a product of same or similar type and condition.

Sum LLC products marked as being a special or a limited edition cannot be guaranteed in case of replacement to be replaced with an identical product.

The warranty does not cover the costs of consequential damage or indirect loss or any related expense of claiming under the warranty, such as loss from inability to operate the product. Products which are developed especially for use in the country in which they are sold, e.g. due to varying transmission systems and approval demands, are not covered by this warranty if defects or malfunctions are caused by the usage of the product in another country.

In order for the warranty to apply, and to claim under the warranty, you MUST include the original invoice (or any proof of purchase) of said product. Images or videos illustrating any potential issues may be required before initiating the return process under warranty.

If the customer would like to return the product for reasons unrelated to the product’s quality, the customer will be responsible for covering the return shipping cost. Once our quality assurance team has received and assessed the product in our fulfillment center, we will issue a refund for the product cost via your original payment method less the shipping cost.
