To avoid the risks of stolen or malfunctioning devices, prioritize platforms with certification programs and warranties.

These are the gold standard. Devices are restored with genuine parts , include new batteries and outer shells, and come with a 1-year official warranty .

These platforms focus entirely on used tech. Gazelle uses a 30-point inspection, and Swappa uses human moderators to verify listings before they go live.

Amazon offers a 90-day guarantee and strict seller vetting, while Best Buy provides solid testing standards and in-store pickup options.
