The phone build is good, but would have been better. It lasts about five days after one full charge. The tracking feature has counter for steps, cal etc. You can find a fit bit with same features in less price. If you touch the heart option it will show the BP monitor but most of the times it shows "tughten watch firmly.blah blah." You have to connect with your phone to get weather info. No calling facility.
A good buy if you want more than fit-bit.
A bad buy if you need a real smart watch.
