I look them up and I like the ideal that you can put a clip on them . Just clip them to your vest and there not dangling off your neck
I went a few years with mine dangling off of my neck. When I got a collar for my younger dog I noticed there was a clip for the controller in the case. I was like dang I wish the other one had a clip. Dug out the case and there was a dang clip in there the whole time.
