We had the box for 4 days and it was a terrible experience. The streaming was scratchy and the remote froze every 10 minutes and it required constant paring. We tried everything to fix the problem. We removed the HDMI cable, turned the box on and off, we also removed and replaced the remote batteries with no luck.
With that frustration, we purchased a Blaupunkt android tv box and we now have zero problems. We do not recommend Xiaomi.
