This band I am using with my android device and I would say it is good fitness band at such price.
It only cost me around 800bucks and it was very cheap deal as other bands are costly.
Yah sometimes it gives little bit wrong rating but we can not expect from cheap product to work like pro.
If you want to use it as a day to day measurement then it is very handy and good product.
It comes with great battery life.
On paper they are saying it last long for 30days but I need to charge it in may be in 15-20days.
Thats fine with me
The feature I like the most is it vibrates before your alarm is going to ring and whenever new notification comes and you are having calls.
Overall I would say this is best deal at such price.go for it
