This remote collar works great with training my puppy. She always like to bark when she is sitting in the car and seeing some strangers out of the window. I set the vibration for 50.(it will go up to 100) and use the collar a couple of days. NO MORE BARKING! Also it hold a charge well and the big remote control screen is fantastic. I wish I had bought this collar early so I do not need to bear the barking.
