Fast, excellent build quality, very price-worthy
Advantages: The phone is very well built and matches the "big brands" in workmanship. The MIUI interface is up to date, fast and smooth with lots of configuration options. Screen is large and bright. 64GB on board is enough for most of us, another 128GB can be used with a micro sd card. Performance is great and I had no problems with any of my apps. Price-performance ratio is excellent. You really won't make a mistake by buying this device.
Limitations: No screen protector included. Camera quality is average, but if you a serious about photograpy you will not use a cellphone for this. Still it is good enough for an occasional snapshot and absolutely ok for casual users. No LTE Band 20 which is an issue in rural areas in my country. Other than that I could not find any issue after 2 months of use.
