Very poor I'll never use Xiaomi again. My experience is similar to others who have reviewed. Ordered a power bank charger with never arrived. Customer Service is rubbish, just keeps coming back saying that they are escalating the issue - I think it is an automated system.After 4 months of requesting replacement or refund, I have given up and getting the credit card provider to sort it out using a "Chargeback". Watch out though, you only have 120 days from original expected date of delivery to report the problem.
