Durable

They came with a wrist band as stated and it looks durable. I'm going to look up how to use them pproperly, but so far it has caught my dog's attention quick. I blew the whistle and she came straight to me. I used the clicker and said sit. She sat instantly and looked up at me with her ears prop. I did think the whistle part would be more of the silent type that only dogs could hear, but I'm sure these will work great. Durable. Pictures on Amazon
