There are so many of these watches and activity monitors on the market! At least the Withings Move has something to differentiate it from the crowd - 18 month battery life, that is incredible!
I have had a fitbit type watch in the past and the battery life wasnt great, so this seems like a great improvement!
Ya the battery life time is the best advantage - 18 months is incredible. Thank you for your kind comment @conradt.
