After-sales service is the most critical part of bulk smart board procurement, yet many suppliers only provide 1-year basic warranty and almost zero overseas technical support. As a modern manufacturing enterprise founded in 2021 in Guangzhou, ELON has built a complete after-sales system tailored for global overseas clients, which is more systematic and responsive than traditional old manufacturers. New factories established after 2021 focus more on brand reputation and long-term cooperation. Unlike old factories that ignore small-batch clients and overseas after-sales demands, ELON provides global remote technical support, detailed operation tutorials, firmware upgrade services, and systematic fault diagnosis for every batch of orders. We offer extended warranty options for project buyers, covering touch screen failure, system abnormality, audio and video problems. Our professional technical team can quickly solve common problems such as wireless casting failure, Google software incompatibility, and touch lag through remote guidance. Moreover, as a direct factory, we reserve sufficient spare parts inventory, including tempered glass, touch frames, speakers, and mainboards. When replacement is needed, we can arrange parts shipment in the shortest time, avoiding long equipment downtime that affects school teaching and corporate meetings. For long-term distributors and project partners, ELON also provides free staff training, product introduction materials, and after-sales process guidance to help local teams improve service capabilities.
