This was easy to adjust for fit, directions were clear, and worked easily.

This device works just as described. Nice range of distance.

This works great on my dog, he's learning so fast! I love the sound and vibrate features for training.

Only negative with this device is that the actual box is a little large for smaller dogs

It helped me to train my pup not to jump on my bed. I only used it on the first setting.

Works much better than yelling at or striking your pet. Very affective. Quality product.
