I bought two, for two of my dogs that bark out-of-control when a bear visits at night, and will continue barking for a long time afterwards. The dogs are inside and safe, but can launch into hours of barking. The unit seems physically way too big and powerful for my little 10 lb. dog, even with the lowest, short burst of vibration. Instead of having the dog wear the collar, I have it hanging on a metal screen door and when I press the remote button to activate the collar from my bedroom, the buzzing noise it makes on the screen stops my dog immediately. So, I'm not using the collars as intended, but I can get sleep on nights when the dogs start barking at visiting fox or bears who swing by to snack on birdseed. I may end up using the collar as intended on my 40 lb. dog for times when he barks excessively during the day or early evening...but I need to be home to push the button to activate the vibration-buzz. It's a good, well-made product, and I really like that it doesn't shock the dog. The buzzing vibration is startling enough to get the needed response.  Read Less
