Before getting the collar, our dog would bark at passers by, the neighbours and shadows. But after wearing the collar and ensuring it's fitted correctly, her barking has significantly reduced. I have used other collars in the past and have found that having to buy batteries often meant they would be flat when I needed them. This new collar is rechargeable meaning it's always good to go. The website was easy to navigate with lots of useful information. Service was great and the collar arrived quickly. Perhaps I should drop some flyers in other mailboxes around me.
