This watch has a very decent look. You can wear your formals or casuals it looks great. Its battery gey charged in 100-120 minutes and which lasts for around 5days in normal usage. It comes for detachable straps so you can change straps yourself dont need to visit the service centre to change the straps. BUT Xiaomi has to work a lot in the research. Its not very accurate. It has internal GPS. So if you are walking with on it simply records the distance and divide by some number and give you a number of steps. It not actually recording a number of steps. Its heart rate is not accurate. It gives very deceiving value. Overall it good to try smartwatch but not to rely on its values.
