[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]: This is easy to use and comfortable. The heat doesn’t last that long and the scented smell is so terrible that I can’t even keep the eye mask on that long.
[EX A]: negative

[EX Q]: Unfortunately I have to give this one star. My first time trying to use it I plugged it in and heard a pop they caused it to move enough to rattle the lid and it won't turn on.
[EX A]:
negative
