I have tried it out on never stops barking neighbour's

Ultrasonic dog trainer repeller worked just fine as described. Very pleased with its performance

Good product, it arrived well packaged and in excellent condition. Only, it took a long time to reach its destination.

Excellent the quite powerful flashlight regarding the capacity of the ultrasound system After the first tests it is totally inefficient as ignored by dogs. I will do some more proof before making the return.

Great to silence the clamps of the dogs. I have already bought three.
