Rated 5 out of 5 by from My 10yo loves it! He did daily 7000-10000 easy with good motivation having it on. very simple function but enough to keep a child run and walk more with visual goals. time and alarm function, family challenge are well used daily. just be aware waterlock need to be set each time before getting it wet, may not be straight forward for young or forgetful children

Rated 4 out of 5 by from Quality Entry Level Watch and Tracker We find this to be a quality activity tracker and watch for our 10 y.o. Bought this as an upgrade to a Fitbit ACE 2. It was easy to set up and has with the added bonus of a better display than the ACE 2. It is minimalist, which is fine as an entry level tracker and watch.
