At BoxWave, we strive for 100% customer satisfaction and consistently seek to improve our products and service. Due to the faith we have in all of our products, we offer the following customer satisfaction guarantee:
30-Day Money Back Return Policy: Products purchased directly from BoxWave Corporation are eligible for our 30-day money back return policy. Products may be returned for either a replacement or refund within 30 days of the delivery date. Prior to returning the item(s), an RMA must be obtained from BoxWave Customer Service. This RMA number must be present on the outside of the returned package. Returns sent in without an RMA may be ineligible for a refund or exchange.

To receive a full purchase price refund or exchange, the returned product must be determined by BoxWave Corporation to be in restockable condition. For a product to be considered restockable, it must be in its original packaging and all parts and accessories must be in clean, unused, and undamaged condition. The returned package must also include a valid RMA number as issued by BoxWave Corporation.

If the returned package does not meet the above requirements, a restocking fee of up to 25% may be charged. This fee will be determined based on the condition of the returned item(s). Once the restocking fee has been applied, a refund or exchange may be granted for the balance of the purchase price.

Shipping and handling charges will only be refunded if a return is a result of (a)manufacturer defect or failure; (b)damage in transit; (c)mis-shipment; or (d)falsely advertised products as determined by BoxWave Corporation. The reason should be noted when the RMA request is made, and must be indicated in the RMA.

The following are exceptions to the general return policy and have specific return policy rules:
  • ClearTouch products cannot be returned if the plastic backing sheets have been removed or re-attached at any time
  • Software purchases are not returnable or refundable
  • Any "Final Sale" products noted as "No exchanges or returns on this item" are not returnable, refundable, or exchangeable.
Please note that all item returns are final. By returning an item (or items) back to us, you are agreeing to the return policy terms and conditions listed above. 100-Day Warranty: All products purchased directly from BoxWave Corporation are covered by a 100- day warranty against any manufacturer defects or failures. We will be glad to set up an exchange for a replacement item within 100 days of the invoice date. Please submit the request via our Email Form with a detailed description of the manufacturer defects or failures of the product(s) received.
