What if the repaired thing breaks down again within three bags?

The year he promised should be a year of normal use, so after the expiration of one year, he added some maintenance time (from filing maintenance to several days of successful maintenance), which means the warranty period can be extended!

So you should have a maintenance record (of course they filled it in).

It's the first charge, and the rest is free.

Dizzy! The same fault is repaired free of charge within one year, and the last maintenance is also guaranteed for one year! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

It should be like this. .......
