Device Condition Quality Assurance
Device Supply is creating the new standard for scoring and valuing tech. Our Quality Assurance (QA) team has developed proprietary strategies over the last decade to carefully sanitize, examine, inspect, score, and value each device that is received by us. This assures the quality of the inventory we are receiving meets our rigorous quality assurance score out of 100.
What is a Device Condition QA Score?
The Device Condition Quality Assurance (QA) Score was developed by our R&D Team to bring a better understanding and level of transparency to the circular tech market. Rather than trying to understand the condition grading scales of other businesses, we set a cosmetic score and a technical score.
The Importance of Our QA Score
Buying used tech can often be hit or miss due to vague and broad grading systems used by many dealers, which are based more on opinion than data. At Device Supply, we aimed to make buying used and refurbished devices safer, smarter, and more scientific. Our QA Score provides peace of mind when buying and ensures a better price when selling.
Our Comprehensive Testing Process
Our QA Score is derived from a detailed inspection process that includes both cosmetic and technical tests. This allows us to assess the condition of your device accurately and provide a transparent, data-driven score.
