the dog trainer collar goes dead fast. must hold button down till you see red, like 3 to 5 seconds. I did not know this at first. so hence xtra batteries. need them for collar only right now. but like having them on hand because once the weather breaks we will be in heavy training outside.
Have a new pup and this has assisted with the dreaded potty training. Have had many dogs in past and sure would have made puppy years a lot easier if I had had one of these for their potty training. Highly recommend!
