I have only had to use it 3 times. My 90 lbs Lab comes back to me now at the dog park instead of barking aggressively and rushing fence! All I have to do is say "easy"! I have had animal control call on me because she gets away from me, not to attack just to go see others. I really thought we would have to use shock collar, something I promised my daughter we wouldn't unless last resort! I'm so relieved and happy with the peace PetGentle has given us.
Bottom Line: Yes, I would recommend this to a friend
