I have allready recommended this item to people. The only draw back i wpuld say is the thickness of it and it is also doubled up. Being its as thick at it is it makes it eassier for my dog to keep pulling. Granted my dog is in tje 20-30 pound range so there is force (shes strong for her size) but the rigidity of this seems to keep it comfortable and makes the correction portion a little harder. This is usually when my dog is at the peak of energy anf excited. When she relaxed ot works as inteded. Im sure if my dog was larger this would be perfect. I do love it and it is my go to so far. My dog is stubborn and a little difficult. This would be a 5 for me if it was maby half the thickness to allow it work ore effectively.
