Input: I was very disappointed with this product. I purchased it for our home to keep dogs away from our 2 children who are always chewing on things. It works only when the batteries in the motion sensor aren't being used too much, otherwise every other night we have to turn off the collar. This defeats the purpose of having an automatic correction when there is no one else around. Our house has 5 dogs and a cat.
Output:
Bad review
