Cosmo JrTrack 5 SE review

Cosmo built the JrTrack 5 SE for kids who are not ready for a smartphone but need to reach parents during the school day. It handles nationwide LTE calling and text, video and voice messages with parent-approved contacts only, and leaves out social media and the open internet. Location runs on HaloGPS, a dedicated chip that Cosmo says gives precise, real-time tracking, with geofences, arrival alerts and location history. SOS alerts go to every guardian, and School-Fi silences the watch in class. A 2 MP camera and App Station with music add some fun. The hardware has a 1.4 inch touchscreen, IP68 water resistance and a 680 mAh battery rated at 18 to 24 hours on default settings. At $129.99 it is the cheapest watch here, but the membership is $19.99 a month unless you prepay, which drops it to $14.99 for a year or $12.99 for two years.
