I bought this device for when my dogs are barking to make them shut up, some feel something strange, but if they are very upset, some do not notice anything and continue barking, my friend says that her dogs react and move away, they are of a different breed than the one. mine. Fast shipping, good seller, regards.

Not an aggressive street dog who went to my side, after pressing the button turned sharply and went into another))) I consider a good effect. I bought it to run in the morning, I also bought a Pepper bottle, because there are reviews that it can not affect aggressive dogs. Not dangerous so you can give children.

And so) good thing. 340R React to the flight of cats, dogs (for some reason not all, it's not about the breed), mice. Cats all 40 of 40 Mice 7 of 7 Dogs 9 out of 11 (both did not react dogs chavki small, fluttering) Thank you.

Got 3 pieces, ordered the same from another seller, there plastic and assembly is better. Here it feels that the manufacture and plastic are cheap. But everything came whole and works.

Laser + led that we can not choose to cut, I took them off because I wanted to be discreet when using ultrasound
