We follow a very thorough inspection process when we receive a device. First, we record the electronic serial number of each item if available. We then inspect the device for damage and usability. Items that are damaged or unusable are securely disposed of through an ISO 14001 R2 certified recycler. Items that are not damaged are checked against several device status databases to ensure the device has not been reported as stolen. If the device is clear, we inspect it for cosmetic damage that may affect usability. If a device is deemed unusable because of cosmetic damage it is securely disposed of. If the device passes the cosmetic inspection, we fully test its functionality and remove all data.
