I really like this collar. It actually works farther than 2 feet from the dog. I think I've used it about 40-50 feet away. I've only used the beep and vibrate on the collar. My dog responds very quickly and it doesn't hurt him. Since it doesn't need the probes to push onto his neck, it's very comfortable for him and he doesn't mind when he gets it put on in the morning.

I am planning on purchasing a second collar to use in training my smaller dog,Thanks for the great support.

I have been using this collar to train my dog. I have found that having the three levels of correction (sound, vibration, shock) is the best way to train the dog. I can just send a sound and my dog will respond to it quickly. The training has happened a lot faster using this collar then without the collar.

I received the best customer support I have ever experienced.

we got this collar, I only have to use the vibrating setting at high level to warn the dogs not to go near the gate and it worked wonder. Now, each time they are allowed into the yards, one by one, with the collar, they know what is expected and did not even attempt to go anywhere near the gate.

I use it to control their barking at strangers when they passed by with other dogs and our dogs, as soon as they hear the music sounds from the collar, will stop barking and returned inside the house immediately. Very please with this collar and strongly recommend it to anyone with problems training their dogs.
