This is an old thread, so you I guess you already found the right fit. For those still looking and on the fence about buying a tracking device, consider using a family locator app instead.
The free app will have you covered (unless you are into pro features). Some of the good ones are: Life360, Zenly, Familo. If you are into a battery friendly option, try GeoZilla: https://bnc.lt/geozilla-forums
You will need to bring a power bank with you though to be safe.
GeoZilla will also show your daily location history, location-based tasks for any circle member, location alerts for when you or a family member enters or leaves a place, private chat, battery status of your family members,
SOS button with your emergency contacts. (Disclosure: I work with GeoZilla, so I may be biased)
