Stay away!
I purchased a Xiaomi Mi10 Ultra on Friday (13/11/2020). I paid via paypal checkout, just with my card details and not with a paypal account. Today (17/11/2020) they emailed to say they are canceling the order because I haven't used a paypal account. Rather remarkably, I have to wait 2 days before a refund. Would highly advise on staying away from this.
