What is your return policy?

Eligible products may generally be returned within 30 calendar days of delivery, subject to our Return & Refund Policy. Items should be unused, unassembled, uninstalled, and returned with their original packaging, hardware, manuals, and accessories. Contact us for authorization before sending a return.

What should I do if my product arrives damaged, defective, or incomplete?
