Returns and Refunds

Returns and Refunds
Returns apply to tangible items only (non-returnable items: services, keys, downloadable software products, etc.). Returns are accepted for 30 days (delivery date indicated by tracking). Returns are accepted for any reason (testing, misdiagnosis, changed my mind). Returned items cannot be damaged by improper installation, exposure to water or fire, insufficient or excessive electric current and/or voltage, abnormal mechanical or environmental conditions, unauthorized disassembly, repair, or modification. Refunds for returns carry a $150 or 28% restock fee (whichever is greater). Shipping costs for returns are not refundable. We assume no responsibility or liability for any damage or loss during shipment. If you are shipping an item over $100, please consider using a trackable shipping and purchasing shipping insurance. You can ship on your own or use our shipping label. To return an item please contact us at, text (773) 800-0041 or
