First of all, we are deeply sorry for any inconvenience caused. You mentioned that you previously found chargers cheaper on Temu and purchased them. We just want to ascertain if those chargers are ours. Out of the 15 chargers you acquired, you reported that 4 of them were defective. Could you please specify what kind of defects you encountered? If indeed these are our products and there have been multiple defects, firstly, we can compensate you for the inconvenience, and secondly, we will work on improving our product quality. However, you are the first customer to report chargers that cannot work. We have not received such feedback before. Regarding your statement that even the chargers you use are unable to charge, could you provide a video or feedback from your customers to assist us further?
