We purchased this collar to train our Labrador Retriever and teach it the boundaries of our land (such as where the road begins) since our land isn't fenced up and we don't want him running into traffic. This device was super simple to set up (thanks to the picture by picture instructions) and easy to use as well. My boyfriend loves that the remote clips onto anything because he clips it into his jeans or his coveralls when it's cold out! I usually don't use the shock mode, I really like that there's a beep mode and a vibration mode as well because it's less intense but still gets the message across most times. I would highly recommend this device to anyone trying to train their dog!
