Lifetime definition: the SERVICABLE lifetime of the product.

This is defined as the period, which is the longer of (a) the period during which spare parts (components) are available for the repair of the product or (b) three years from the date of manufacture of the product. Should the product prove to be irreparable within the serviceable life of the product, Brainboxes reserves the right to substitute an equivalent product.

This warranty shall only be valid in respect of goods subject to the following conditions:

  • That such goods have been paid for by the due date.
  • That such goods have not been subject to abnormal working conditions, wilful damage, accident, physical damage, fire, flood, negligence, misuse, alteration or repair of the goods without Brainboxes’ approval, or a failure to follow the manufacturer’s instructions.
  • That any alleged defect or shortage in delivery is notified to the company within 7 days of delivery or within a reasonable time of discovery of the defect or shortage if not apparent on delivery.

Return Procedure

If a product requires repair under warranty, Brainboxes will either repair or replace the product at its sole discretion. If you need to return a product under warranty, please contact Brainboxes support team to request an RMA (Return Merchandise Authorisation). No products will be accepted for return without a valid RMA number. Products must be returned in the original packaging or equivalent packaging, which will protect the product in transit. The customer accepts responsibility and cost for the safe return of the product to Brainboxes.


This warranty does not extend to products which have been subjected to misuse, neglect, accident, fire, flood, physical damage, incorrect wiring not of our doing, improper installation or testing, unauthorized modification, use in violation of instructions furnished by us or repair by an unauthorized third party. In such cases the warranty will be void. This warranty will also be void if the product’s serial number or other identification marks have been defaced, damaged or removed.

There are certain components which have a finite lifespan. These components are covered up to their typical lifespan. For example the ED-538 contains relays which have a typical lifespan of 100,000 operations (at 2 Amps). The Brainboxes Lifetime Warranty does not cover these relays past their typical lifespan, all other components on the product are covered by the Lifetime Warranty. Further exclusions still apply.

The Original Purchaser’s rights under this warranty are as expressly provided above. Brainboxes shall not be liable for any losses, costs, expenses or damages whatsoever, other than the repair and/or replacement of the product as provided above, including any loss of profits or other damages resulting directly or indirectly from the failure or defect of the product, save for any liabilities which cannot be disclaimed or limited by law, including liability for death or personal injury resulting from negligence, or liability for death or personal injury or non-commercial property loss or damage resulting from a defective product. The contract formed upon acceptance of this warranty is not a contract for the sale of goods to which the Sale of Goods Act 1979 (U.K.) (or any successor legislation) applies. Your statutory rights are not affected by this warranty or its exclusions.
