What should I check before buying from Costco Refurbished?
Confirm the grading scale and whether it covers internal components, the disclosed battery-health floor (80% is the accepted minimum), who issues and services the warranty and for how long, and the return window. Under the Magnuson-Moss Warranty Act written warranty terms must be available before purchase, and most states imply a warranty of merchantability on refurbished goods sold by merchants.
