Review on PETPNR Devices Ultrasonic Rechargeable Modes：Drive Training，LED Dogs by Tasha Murphy

This little thing really works. I put it on training mode and my pit bull pup stops everything he's doing. If he barks at the neighborhood kids, he stops immediately. The battery life is excellent. I've only had to charge it twice in as many months. I would have thought it was waterproof because I left it outside during a downpour and it still works. All I did was let it dry before trying to use it. I am thankful for this little car because it saved my pup from a collision. He ran out into the street and sped into oncoming traffic. It's good that I always hang it on a string around my wrist when I go outside with the puppy. It stopped him in his tracks as the car sped past, narrowly missing my pup.
