Frequently Asked Questions
A refurbished device is a pre-owned product that has been professionally inspected, tested, and restored to full working condition. Any faulty components are repaired or replaced, the device is thoroughly cleaned, and all key functions are quality checked to ensure reliable performance.
All our refurbished devices come with a minimum battery health of 80% or higher and are cosmetically graded to help you choose the condition that best suits your needs:
• As New: Like new, with little to no visible signs of use
• Excellent: Minor cosmetic marks that are barely noticeable
• Good: Visible signs of use, but fully functional and performance-tested.
