I would give this collar a 5 except that the snap can get sticky and hard to release eventually the scissor end came off the little loop. I haven't been able to get it back on. It did last for 2 or so years.
Would be rated 5 if it had come with instructions - after I was taught to use it - it is very easy to use and my dog behaves very well with it on.
