I am using this fitness tracker for about a year now and this is good for you if want to know your footsteps and calories burned.
It’s good and waterproof and I can go to bath even when I wear this . This has a great battery life of about 30 days which is good enough for everyone.
I compared this with fitbit smartwatch for its accuracy and it’s almost the same. And one thing I think has to be the heart rate sensor. Then it will be ultimate I think . Hope next version has that
