5.0 out of 5 stars Setting it up
Reviewed in the United States on April 17, 2024
Color: Blue Astro GreenVerified Purchase
People have had many issues setting up the family account and just send it back after not solving the problem. I had the same problem, but all you have to do it make sure your kids account is on your kids phone and make sure you have the fit bit app on theirs, set up and ready, if you do then you should have no problem setting everything up. Overall it is a great watch to have. I bought it for my little sister for her birthday and she’s loved it ever since. 10/10 But after a while of them growing up with the fit bit just buy them an Apple Watch.

5.0 out of 5 stars Garmin vs Fitbit
Reviewed in the United States on February 23, 2024
Color: Blue Astro GreenVerified Purchase
After reading several negative reviews on the Garmin kids’ watch, we decided to go with the Fitbit and haven’t regretted it a bit. My daughter loves to see how many steps she’s taken at the end of each day, and having an alarm feature is an added bonus. If you’re on the fence about which kids’ activity watch to buy, let this be your sign to go with the Fitbit.

1.0 out of 5 stars App and software highly annoying for the Acer 3
Reviewed in the United States on April 28, 2024
Color: Blue Astro GreenVerified Purchase
Trying to set up my daughter’s account for her today. The app tries to push Google emails and family set up on you instead of just allowing your child to make an account and get to moving.

Instructions on how to do this are extremely convoluted and unhelpful. Google instructions on the matter refer you to the Google Play Store or to your Android device settings. Unhelpful if you have iOS.

I figured a way around it by logging into my own personal Fitbit account on my personal device/phone, adding a child from there, then logging into the kids device with my personal Fitbit profile, then switching over to the child’s profile.

Absolutely outrageous in this day and age for it to be that difficult. It took me, as a reasonably tech savvy person a good 30 minutes to get this set up, when it should really have been wearable right out of the box. Don’t allow kids with the Acer device to make purchases. Is it really that hard?

I wish I’d just gotten her the regular adult device.

(As an aside, I did succeed in making a Google family and adding my daughter to the family. In the Fitbit app the “add child” link was broken and she never appeared in the app to load her profile, even after doing all that. If some of this is just me being frustrated late at night, not all of it is. This should not have been an issue.)

4.0 out of 5 stars Decent pedometer, terrible band.
Reviewed in the United States on June 24, 2021
Color: Blue Astro GreenVerified Purchase
Cute pedometer for littles. My daughter is 6 and has been begging for a fitbit like mommy and daddy have. It is just the right size for her tiny wrist, however she had a reaction to the silicone band. At first I thought the watch burned her but we got a new band and she has been wearing it the same amount of time and the skin iritation and mark is gone and she hasn't gotten another.

We originally got it to see her sleep patterns. Granted it has no technology to really tell if they are asleep and no HR monitor it just guesses by lack of movement. When she wakes up she can look at it and easily read if it is time to wake up or if she needs to roll back over.

She also loves trying to beat daddy in his daily steps but he is very active at work and not the easiest to surpass, but she still tries her hard.

Overall I give it a 4. She loves it, only takes it off to charge it or when she washes her hands due to the cloth band we got for it. (She doesn't like a wet band on her wrist)

Reviewed in the Netherlands on February 18, 2024
Color: Blue Astro GreenVerified Purchase
This was a gift for my Niece, however, due to waiting for my family to arrive here, it was too late by 3 days to return it. Could not get it paired or connected to my Niece's phone, no matter how many times we tried to family link it through her mums google account and phone. Would have been sent back if time had not run out. Not a very good system to connect it and gave up after 3 hours and a lot of online searching for a fix to this. Very disappointing. Beware of this when purchasing. After another 3 hours, I finally figured it out. Need to malke sure the phone for the child is actually logged into the childs account and setting it up is done via the parents phone. The instructions are not that clear and after quite a lot of google searching, made it work.

Reviewed in Belgium on December 4, 2023
Color: Blue Astro GreenVerified Purchase
Het product zelf ziet er leuk uit en zal veel potentieel hebben. Maar het grote probleem zit bij de installatie. Het is onmogelijk om een kinderaccount toe te voegen aan je eigen Google account en deze dan te linken aan de Fitbit. En voor een oplossing wijst Fitbit naar Google en Google wijst naar Fitbit. Zeer frustrerend. Gevolg: Fitbit teruggestuurd en een andere smartwatch gekocht.
