I would not recommend buying it in India - see my reasons belowWhen it was working , it motivated me to exceed my perceived limits and I improved my daily running . Hit my goals better than ever . The great convenience of effortless tracking daily steps, calories burnt and heart rate was delightful. Charging once in 4 days in the beginning without GPS really being used. I used to run on the treadmill wearing this and wear it constantly even when asleep. All this lasted exactly two months, when the first one started synching erratically and then stopped synching completely. Please note Surge does not allow you to synch using the cable . In effect Surge turns completely useless when this happens. I got a replacement quickly from Fitbit. I was delighted and continued for another 1 months. The second failed exactly in the same manner a week and half back when I was travelling . It was my only watch - so it caused quite a bit of frustration and pain. So far Fitbit has not sent a replacement nor would they give me a refund. The stock answer is they are processing this. No questions/responses on what could have caused this. I tweeted their CEO James Park - I got a stock response from their support. So if you are in India and are planning to buy this, I would suggest you look at alternatives too - Microsoft Band 2 perhaps. Dont rush into buying Surge without checking warranty and support.
