Henrys fit bit
This has been a great addition to assist Henry to keep active and challenge himself to complete his daily step goals. Also helps with his awareness of the time and getting ready for school each day.

She loves it!!
My 8 year old loves her fitbit. She's so proud of herself and amazed by the number of steps she does through the day. 20,000 yesterday! You would have thought she'd won a gold medal :)

Great kids watch and fitness tracker
A great fitness tracker for kids. My son has been using this for approximately 6 months now without fault. Easy-to-use and sends me weekly emails to update us on his progress daily step count. Battery low warnings,and it lasts at least a week before recharge. Very happy with this fitbit product.
