Great for kids
I purchased this watch for my son’s 5th birthday and he loves it. It’s great that we can easily change the clock faces and some, like the monster in the box, grow during the day according to how much active he is. It has functions like timer, steps, alarm, hours of sleep and the app it’s very easy to setup and use. I like that the numbers are quite big and it’s good for him to practice numbers recognition. The watch it’s light weight and and says it’s comfortable to use.

Fitbit, For fit kids!
Great way to motivate kids to be on their feet. My 6 year old loves to brag about how many steps she has taken. No other frills other than a step counter and basic watch functions, which is perfect for us. The battery lasts pretty long enough and gets charged quickly too. The strap, as mentioned by some, needs replacement after just over a month of daily usage. Waiting for my replacement (available only International delivery)

Kids like them, helps them to be active. Pairing is easy, quality is good. Got sleep monitor which i used for my kids. Only complain is charging cable is too short; you’ll end up charging the watch on the floor and can easily be detached from the watch. More features added to the watch will be great also.

adapté aux enfants. super... mon gamin trouve cela très ludique pour la marche comme pour le sommeil même nous cela nous permet de nous rendre compte de leur activité journalière... ca peut etre assez surprenant des fois ... L'application de base nécessite un adulte pour avoir un compte pour l'enfant

Love this Fitbit for my kids! We purchased 2 for our twins almost a year ago to help them track activity. We had no idea how much they’d love them! Their activity went up & they started making sure they were getting their hourly steps in. 2 x we’ve had one go to a blank screen & while being fully powered. Each time we’d place it on its charger and wait a few mins. Within 15 mins it’d be back to normal. The watch is easy to wear, flexible & comfortable. The kids leave them on 24/7. VERY happy with this purchase!

Muy buena opción pata niños ya que no solo le dan información de hora y pasos si no que además anima a alcanzar objetivos de pasos ya que salen varias sorpresas y eso les encanta. Material resistente y se puede personalizar un poco la pantalla.

Bought this purely for the sleep tracking and the reminder alarms. Has MASSIVELY helped our little one with her anxiety at school about going to the toilet by setting alarms and letting her teacher know what we’ve done. The little duck quacks on screen (vibrates doesn’t make a noise) and she knows it’s time to go :) It’s helping us track her sleep versus her focus, concentration and general happiness She loves competing with mummy and daddy on her steps (always wins of course) but that’s just a bi-product for us as it’s not what we wanted it for. It’s not a smart watch so she’s allowed it at school and she likes changing the cartoon face each week :) Great quality, wears it all the time including in the bath and for swimming, it’s a great colour and is very durable. Plenty of growing room on the strap, easy to set up and only needs charging once a week. Just Top Notch!!
