Not great at all

works great

Is to limited distance. And some times don't get the signal

Junk. Range is only within a room.

Basically worthless. It attached to my phone easy enough then I put it in my pocket and sat watching tv for 3 hours during which time the alarm went off 8 times saying the device was out of range. Randomly connects and disconnects causing errant alarms.

It's small and lightweight pretty good for smaller pets. I'd prefer small though. We were excited, but the button on the front is very sensitive and our dog just laying her head up and down sets off the beeper and continuously disabling the sync with the phone. Didn't seem to be as much of an issue with the cats. However, it doesn't even work outside of one room.

These units are useless.

Very good
