I bought this product from flipkart at rupees 1999 and the band is just ok and I would not say that it is a value for money but its also not that bad. The product has a lot very good built and it feels really comfortable in your wrist and is very smooth it doesn't feels a bit uncomfortable and the reason why it is always in my wrist.
But talking about the other thing than the built th product hardware or software you CA say is not that much accurate and the information displayed by it is almost wrong all the time like foot steps takes are sometimes 5000 when I had just walked not more tha 2000 as I did do any extensive exercise. Also the battery life is just average with just a 12 days of backup and sudden power shutdown
Also sometimes the mile run is also wrong and I am not very satisfactory with this fact. It can used also used for notification purposes and vibrates on call alerts or notification. But that is really all it does and I don't find any sense in spending that much money use it as trendy watch as the information is also not correct and the reason I won't recommend as you don't get what you pay for.
