Short version: we are a catalog, the purchase happens on the retailer’s official listing, and so does the return. We cannot issue refunds because we never take your money.
The standard return window at the retailer is 30 days from delivery. Beyond it, OKAIDI handles defects through the manufacturer contact listed in the box; keep the order confirmation, since it doubles as proof of purchase.
Test the whole kit within the first week: full range walk, one night of ECO mode, both cameras if you bought two. Nearly every real defect shows up in the first nights, safely inside the window.
