保修都是要凭发票的,如果没发票的话有些品牌按出厂时间进行保修,有些不保修。 但是亚马逊网购的商品的话大多都是亚马逊自己提供的保修服务,也就是要寄回亚马逊,它修好后再寄回给你。
也有部分是可凭发票到实体售后点维修的吧,具体要看你买的是什么商品了。
Warranty requires an invoice. If there is no invoice, some brands will provide warranty based on the time of manufacture, while others will not. However, most products purchased on Amazon are provided with warranty services by Amazon itself, which means that you need to send it back to Amazon, and it will be sent back to you after it is repaired.
Some products can be repaired at physical after-sales service points with an invoice, but it depends on what product you bought.
