Been using this product since last year and I found it very useful.
This is a very good product from Xiaomi from very little cons.
Pros:
1- This is a quite affordable fitness band(one of the cheapest)
2- Tracks your steps very well. its quite accurate
3- Battery backup is damn good.
4- I think its a perfect value for money, now it comes for around INR800 and I feel its still worth
5- Looks stylish too.
6- Its not complicated at all, easily pairs with the phone
Cons:
1- No display(Can ignore it looking at the price)
2 Material quality would have been a bit better
