Grest Inspection and Grading
Grest Grading is our way of carefully evaluating and categorising the condition of devices, ensuring transparency and accuracy. Unlike many dealers who use grading systems that are too broad and depend on personal opinions, we use a more detailed approach for a clearer understanding.
Our evaluation process includes a 50-point diagnostic test. This comprehensive test examines various aspects of the device, guaranteeing a thorough evaluation. We prioritize concrete data over subjective opinions, providing a more reliable assessment of the device's condition.
Our grading system distinguishes devices into three categories: Super, Good, and Fair.
This clear and detailed grading system ensures that you know exactly what to expect when purchasing a device from Grest.
Conditions

The phone you will receive is in superb condition. While there might be a few extremely faint scratches on the frame and screen, there are no significant signs of usage.

The phone will exhibit noticeable indications of use, including scratches and blemishes on the frame and screen. The screen scratches are hardly noticeable when the phone is powered on.

The phone displays numerous marks, dents, and scratches on the frame, with visible scratches on the screen. However, the screen remains uncracked and fully intact. When equipped with a case, this phone will perform just as capably as any other for your daily needs.
