I live with 2 American Bullys that are completely the opposite in personality. One is a couch potatoe and doesn't go far from the couch, while the other is very active, runs around, and has barking issues.
Sometimes the active dog just will not listen, especially if the Tarc bus is letting people off right by our house. I am able to use the vibrate feature to get his attention deterred from what he is barking at to respond to me.
I never tried the shock feature as I don't think my dog needs this feature used, the only thing that I would change is possibly marking this button red, so you don't accidentally hit the button when using the remote. You can do this with a permanent marker like I did.
I have been very happy with this collar, it quickly gets my dogs attention when he is in a barking fit with total attention on what he is barking at. I received this set at a discounted price or free in exchange for an honest review.
