As a platform for buying and selling second-hand mobile phones, the second-hand mobile phone platform has always been very chaotic, and the quality of the bought and sold mobile phones is sometimes really difficult to guarantee.

Moreover, there is no third-party guarantee for this platform, and the funds can't be well guaranteed after customers pay on the platform. It is not safe to pay directly with Alipay.

It is difficult to guarantee the quality and after-sales of second-hand mobile phones, and the platform is still insufficient in this respect. Moreover, the after-sales team looking for this platform is not perfect, and the maintenance price is relatively high. Therefore, it is very troublesome to apply for after-sales service when there is a problem with the mobile phone.

The platform is for online sales, so it is difficult for customers to see their mobile phones on the spot, so it is difficult to grasp the actual needs of customers.

Moreover, as a new platform, the platform for finding American mobile phones is relatively lacking in capital and operation, and its ability to resist risks is still weak. The technology to distinguish whether some mobile phones are refurbished mobile phones is still lacking.
