Excellent product. My daughter gave me hers that she previously purchased and I had used it for my great Dane I only had to use the shock on it one time.

Will definitely recommend to other pet owners as this has changed the bad habits our puppy was learning.

Best training collar ever

I tested it on myself and the vibration is definitely strong, the battery life came full, lock feature works like a charm. My dog is as stubborn as he gets, he wrecks everything in his pathway so I know for sure this will definitely help my situation. Can't wait to start my dog training.

battery life is still full, very impressive.

Exactly as stated
