I have the original Herm Sprenger prong collar and I absolutely love it. I wanted to try out this variation since it has a quick release rather than opening/closing via prongs. I think it's great for someone that doesn't have the dexterity to open the prongs; however, I felt as though it didn't fit the same as the original collar. It always felt somewhat off, no matter how many prongs I removed or added. My dog is between sizes so I usually need to alter the collar, which worked fine with the original. It might be more effective for a dog that fits better.
