[EX Q]: I never wanted to be a dog parent that needed one of these, but here I am. I have a year old puppy that will not listen when it comes to eating things he's not supposed to outside. It's super easy to use and I love that there are different settings. I mostly use the vibrate but when I do need to use shock I have to use at least 80 for my dog to even notice it. My use of the collar is to have my dog drop whatever is in his mouth from a distance so a lower setting might work for your dog. There's a charge port to put the collar and remote on which is awesome. The collar is also super long but you can trim it to fit.
[EX A]: positive

[EX Q]: The first battery did not work more than a month. They sent me another one and that one was even worse. After purchasing a new Shark Navigator, I put the Shark battery in my old vacuum and it worked. Then I put this off brand battery in my new Navigator and it did not work. Clearly these generic batteries don't work.
