I'm glad I ordered these.I have two sausages.One is one year old, the other is 11 years old, deaf.The dog is still learning not to bark at dogs or people while walking. What about the other one?She just likes to bark.I've been using this for 2 days and I like it now.I can beep or vibrate both collars at the same time (it does vibrate, which I will avoid) or turn a collar to correct the dog.It's great logistics fastThere is no error in the object and picture.It looks good on a dog
