I have been using this watch for 8 months this band is a bit expensive as compared to mi band 1 and I dont think you should go for this one , this band can be used as a watch and a
smart band and also has heart rate feature which is good addition but not a very accurate one ( Won't
know why do we need if we are looking for a fitness band to do excercise)
Pros:
Very cheap and best connectivity with phone.
Accurate steps count ( Not like fake info of lenovo bands)
3.It have a sensor to turn on the lights of the band automatic
ally to show date, time and day on screen, by just twisting the
wrist. Like we do to check time usually. ( My best; )
More than 15 days battery backup by a single charge.
Excellent sleep data even at day time.
Light weight, easy to wear.
Completely waterproof
Cons Only the auto light on by twist is not fast and frequent,
It is much more expensive as compared to mi band 1and would tell you to skip this one and go for hrx version instead
