The display can be personalized to fit personality as the watch comes with an online site where you can get faces installed in the watch. There’s even an option that allows users to customize the watch faces. It is also capable of connecting and controlling music without requiring third-party apps to do so. With regards to its monitoring capacity, it does offer an easy-to-understand reading and can be personalized through the app. It also alerts users through vibration and it comes with a long battery life.



However, the smartwatch does have a few drawbacks when you purchase it. Although it has available accessories, it can be difficult to remove the main system from the band. This also makes it difficult to charge up. Some complain about the band being a bit cheap and some parts are not properly aligned to one another. Moving across the programs and apps through the tracker also takes time to get used to and it does not respond very fast. Records are also inaccurate and there are times it cuts off. There are also reports that it does not track sleep or detect heart rate. Connectivity issues have also been reported for some devices, especially those running with updated Android software. Those who purchased the smartwatch also warn other users that the device may have support issues in English since they were given a Chinese model.

Which one to buy? 

Smartwatches that also double as fitness trackers do have a lot of appeal for many who wish to stay fit despite their lifestyles. Both of these smartwatches we reviewed both have the features needed for a fitness tracker that won’t dent your budget too much.

If you want something that is tried and tested, the Fitbit Charge 3 is the one to get. It also has features like contactless payments and 15 exercise modes that the Mi Smart Band does not have.

However, if you want something that is cheap but can still help you monitor your movements, the Mi Smart Band 4 is the one to buy.
