As followup to my previous review in 2015. I had to epoxy this collar to make it hold its size. The buckle kept slipping so that it was to loose during use. Now that my Belgian shepherd is 3 years old, he has finally quit growing (I think). I need a new collar to fit his larger neck. I will epoxy the new one to size again. That being said, I love this collar and the excellent training results achieved using the educator ecollar system. With and only with proper user education, this tool is a fabulously effective and humane tool for canine training.

I bought this nylon collar is replacement for the original plastic Educator collar. This is a far superior design because of the quick snap buckle and the nylon material. You can easily adjust the size to fit your dog and leave it. Just snap it on and quickly check the fit, then proceed with your training. No more struggling with the buckle, adjusting the fit every time we use the e-collar. I cut the excess collar away for my six month old Belgian Shepherd puppy. The price is so reasonable I don't mind buying a second or even third one as he grows I highly recommend it.
