Radiant Opto-Electronics is committed to "achieving customer satisfaction," which it prioritizes in the delivery of its products and services. Radiant Opto-Electronics provides comprehensive technical support and on-site services. Upon receipt of order and within the warranty period, customers may contact our customer service personnel to arrange for return, exchange, repair and transportation, if they have any problems or concerns related to product quality. In addition, the customer service department collects client information, regularly reviews and monitors the Verified Line Reject Ratio (VLRR) to assess quality performance. Through failure analysis, the Company addresses in-factory anomalies, develops integrated solutions, and takes practical actions to meet customer requirements, delivering higher-quality services and more competitive products to clients.

The Company also conducts an annual "Customer Satisfaction Survey" to assess whether it has met its five service goals: "delivery," "quality," "service," "development," and "harmful substances free/green products." Based on the feedback, the Company continuously improves in areas of customer concern. In 2025, the overall customer satisfaction score was 95.00, an outstanding result. This demonstrated Radiant Opto-Electronics’ steady growth in customer satisfaction and affirmed the high quality of Radiant Opto-Electronics’ products and services. Furthermore, in recent years no products delivered to end customers had been recalled due to quality defects.
