I am using the MI Band 3 since last 2 months and so far I have noticed that this is an excellent product in terms of both user experience as well as in terms of value for money. This product has a Heart rate monitor which helps me to count my heart rate when I do my workout, other than this it has features like Step Counter, Calorie Counter, Stop Watch, Alarm and much more my Friends. The biggest thing to appreciate about this MI Band 3 is its Battery Life which last for 21 days minimum as claimed by the manufacturer Xiaomi but I have noticed that my product easily gives me a battery life of 26-28 days which is mind blowing because no fitness band offers you such a good battery life and also packed with heavy features and proves itself a great value for money product which only comes in a price tag of Rs 1999/- only . I would strongly recommend you to buy this if you are looking for a fitness band which is in budget range and which offers a great value for money. Don't think if you are willing to buy it but just go for it because it is the best which you can get in such a cheap price
