With a 20-year history, CDI has become one of the largest remarketers of computer equipment in North America. But our standards are as tough as ever. Before any piece of equipment can earn the CDI-Certified seal, our technicians put it through the most stringent testing, cleaning and auditing procedures in the industry. Each piece of equipment is cleaned internally and externally. Systems are verified for functionality and performance. Monitors are tested for clarity, brightness and color range. And then, we put it through four intense quality checks to ensure that when you install that piece of equipment, it operates as if it were new.
