good
I really love the fact that this is waterproof and sleek. My dog is not offended my wearing this and it doesn’t bug him at all. It has a lot of different modes and everything is charged by a core that plugs in to any home outlet. I really enjoy this unit, I don’t personally believe in hurting my dog, but he also barks a lot at random things. This allows him to concentrate and not be scared. I love the design and I love the fact that I don’t have to buy batteries for this.
