This is the 3rd time I've ordered this same collar. Works for large and small dogs. Easy to use and highly effective. Definitely would buy again. Great value.

Had trouble with the initial testing but watched the video and it was my error. Works exactly like it should. Stops her after the second bark on the medium vibration. Much more peaceful for her and us!

I like how sturdy the collar is.

Collar worked great to train my dog to control barking. Can be used with or without shocking my dog, and the strength can be adjusted. The collar also has a vibration feature that can be adjusted. Collar comes with a handy cord to re-charge the collar via a standard USB port.

This is easy to use and easy to understand. It helped immediate! The dog no longer barks! Recommend this!

The product is very effective and keeps my German shepherd quiet during the day when cars and people are walking around. Very durable and long lasting and the rechargeable battery is a plus!
