The button to turn on and off is poorly placed and designed. My dog shakes his head and it shuts off, can be hard to turn on sometimes, and then it just turns on by itself sometimes, wasting the batteries, which don't last that long to begin with. I hang it up when not in use and one night I awoke to flashing lights cause it decided to just turn on. Very glad I didn't spend much on this item!
ConsHard to turn on and off but at the same time my dog only has to shake his head and it shuts off, so then I can't see where he is on my two acres
