A:AnswerThe other model has more substantial features in the app that requires the heart rate so if you are looking for simplicity just to track your steps and have something easy to use, this is certainly a great choice.
A:AnswerCharger is included and it plugs into a USB port to charge. It has a magnetic type charger to charge the device.
Cord is kind of short though.........
A:AnswerNo. It does requires Wi-Fi to download the Fitbit app and to count and track your steps. The information can then be documented on your personal information that is loaded on the app on either a computer,pc, laptop, etc.
A:AnswerI wear mine on my ankle. I've had to cobble all 3 pieces of the band together to make it work because they don't make longer bands. I'm usually carrying something at work and discovered that it didn't accurately capture all of my steps. I'm also not allowed to wear it on my wrist during karate in order to not injure anyone, but i can on my ankle. It's as accurate on my ankle as it is on my wrist.
A:AnswerYes - my 10 year old grandson and 12 year old granddaughter both love theirs. He has the black band and she has the sangria band. It works great for them and they seem to really enjoy them.
