I suggest you to be careful with this. Some of them can be with some flows. I just have read in this article https://www.myfrugalbusiness.com/202...ne-xs-max.html that some iPhone XS Max can come with some issues from the beginning. Some of them can come with bad cameras, they won't do good photos. You can have bad Wi-Fi and data connectivity and overall speed, then you are not alone. This is an issue that XS and XS Max users have faced. There is a fix for this, you can find it in that article if you have this issue. There are some issues with the charging, some iPhones won't charge.
Do you have an offer for iPhone XS Max ?
