Great product
My child absolutely loves it and wears it everyday. it’s such a good way for my child to track their everyday activities and we can have a competition to see who does more steps they always win. Battery life lasts a good few days maybe more over a week. Took a couple of days to for them to figure out how it all works. But once they got used to its functionality they were good to go. Would definitely recommend.

Works well
8 year old daughter has this and she likes it. It’s a bit fidgety to work out all the menus and get out of water mode but has plenty nice downloadable faces that she likes. She uses it all day and keeps it on when swimming. No issues with any glitches. A good size for smaller wrists.

Do not buy: Life is to short for UX this bad, buy anything else but not Fitbit!
Since Google took over Fitbit, the experience has become genuinely dire. Setting up the Fitbit Ace 3 is an absolute nightmare. You must use a child Google account, but a child cannot set up and manage their child account to become a Google Fitbit account. This forces you into Google Family Link, which then prevents the Fitbit app from working properly. You are pushed into an endless loop of sign-ins, permissions, log-outs, and errors with no way forward. After Months of trying, reinstalling apps, changing settings, and following Google/Fitbit’s own instructions, the device is still unusable. This is a children’s product that requires adult-level technical patience and still fails. But i now have nearly 20 Google Accounts! The user experience is so catastrophically bad that it renders the product worthless. Save your time, your sanity, and your blood pressure. There are far better alternatives on the market. Do not buy this. Buy anything else but not Fitbit.

Great product once setup*!
My 7 year old daughter loves this product, it works really well, is easy for her to use and the battery life is really good. The only negative is that setup was a real pain. The challenge was adding my daughter as a child to my Google Account. In the end I gave up doing it on my phone and ended up needing to do it all on a different device and it seemed to just work. So in summary, amazing product but difficult to setup!

Great device for kids
My son loves his Fitbit. He enjoys tracking his sleep and his steps in his watch. It’s the perfect fit for for him and is adjustable. The battery life is brilliant it lasts for days. Easy to figure out how to use the features of the device and was easy to connect to Bluetooth and WiFi. When he gets a phone of his own we will upgrade to a Fitbit that can connect to a phone but for now this is great for him.

Tricky to setup and irritates skin
We got the Fitbit Ace 3 for our kids, and while it’s an ok fitness tracker, the setup process and syncing have been more challenging than expected. Also, the watch strap irritates their skin meaning they take them off regularly. Here’s how it went: Pros: • Reminders: You can set the watch to vibrate at certain times to get them to drink water. This worked really well for our kids. • Motivates Activity: It’s a great tool for encouraging kids to stay active. The step tracking, challenges, and animations are a big hit, and it’s helped build healthy habits. • Battery Life: The battery lasts a good few days, which is a relief because I don’t want to charge it every night. Cons: • Setup Was Tricky: Getting it up and running was not as straightforward as I’d hoped. Setting up the child’s profile and pairing it with the app required some trial and error, and the instructions weren’t very clear. • Skin irritation: The two photos are attached are my kids wrists after the watches have been off for 3 days. You can see they are still very sore. This makes them not want to wear them. They aren’t normally sensitive to things and have worn other watches before without this issue. • Tedious Syncing: Because the children are too young to have their own phones it is annoying trying to get them to sync to my phone to see any insights so we don’t bother. • Limited Features Without the App: Some of the features rely heavily on syncing to the app, so if syncing fails, it feels a bit pointless. Overall Thoughts: The Fitbit Ace 3 is great for encouraging kids to be more active. However, the setup process and syncing issues take away from the experience, along with comfort issues. I wouldn’t buy these again, personally.

My little one just loves it.. connected it to her phone and now she has a challenge to do more sports and steps.. She is a swimmer, so this water proof feature helps her see how much calories she did. She really loves it and charge it as soon as its empty. Which takes a long time to get empty and short time to charge. Thank you FITBIT :) Happy Kids, Happy Parent. I do recommend this product. SSM
