I am not sure who won the fitness device race yet!! I think the technology needs to improve a lot when it comes to battery,accurate reporting and data syncing I have used fitbit surge and chargehr.Both are not good with syncing over Bluetooth but battery life is gud because of monochrome screen.Reporting of steps is OK but I see it not counting basic steps at times.But surge looks really bad on your hand. Moto360 - horrible battery life and in accurate reporting. iWatch- my friends told me battery life is not great Microsoft band-horrible battery life. Most other fitness watches or devices I heard battery life is a problem or Bluetooth pairing and syncing has problems.May be that is a problem with Bluetooth itself :). You cannot charge your watch or band everyday,at least not me.I have not come across a good fitness device which has good battery life and reasonably good smart watch capability and very stylish looks.Does anyone of you have good experience with fitness+smart watch device ?
