Great product. But not fit for small dogs.

Battery last for weeks. Many shock levels to choose from, will go very light. Lock feature is nice and prevents accidents. Vibrate works well.

All the modes it has does good for training dogs

Had all functions I wanted plus the lock option.

This was a game changer for my pup! Works great!

I like that this really has help me with my dog who barks at everything. From other dogs to door bell rings, he's much more calm
