Great idea, poor execution The battery life is too short, the chargers are unreliable, and the app is incredibly hard to use for anything. It takes entirely too long to connect to my collars regardless of whether I’m using Bluetooth, cellular, or GPS. If I need to see where my dogs are or send feedback when they’re barking at coyotes in the middle of the night, I can’t. And unlike Garmin, rather than adding another collar to the system, it’s another $500+ for a second collar plus another monthly fee. I’m still using the collars but will get rid of them as soon as I find another option.
