The quality of the product is average. After a few days of use, the bearing made an abnormal noise, which was later reported to the after-sales service and technical service.After confirmation, it is agreed to reissue the parts.One week after the delivery order number was sent out, it was a big black dragon (actually it was not sent at all). Later, I always hoped that after-sales could help solve the problem, but after another week, it still could not be solved!It's really helpless.
