Rui Aili's after-sales service is not so good. When she bought it, she said it would be free for life, but if it really needs maintenance or repair, she has to take a ticket when she buys it, which means that this ticket must be kept as long as you bought it ... this is a burden for customers! Business with such regulations will not be sincere business. So I won't patronize the brand of Rially any more.
