We have used petsafe wireless fence for about 5 years. We love it and it has always worked very well with all of our dogs. Only down fall is the collers will fall off every blue moon or the black box will fall off no matter how tight the screws are. I have had to buy 2 extra coller because my dogs have lost theirs and we can't find them anywhere on our land. Other thing is batter life, they do drain quicker then I would like so we have to stay stocked up on them at all times. But we do have stubborn dogs and the coller have to be put on 4 or 5 and they also wear their coller 24/7 since they come and go as they please.
