Good for items u don’t want to leave behind like purse or keys
I don’t know about dog tracker as the keychains only last about 30 feet. And to the other reviewer the beeping is stopped if u turn off the alarm when disconnected. Basically if you leave range the alarm will go off so I like it for my purse and keys.. perfect for them actually it will save me invade I ever walk away leaving my purse in the restaurant again or my keys at someone’s house both I’ve done. The app lets u see it’s location if connected and in range and last location if disconnected renaming and changing sound is nice wish the battery lasted longer tho
