So far so good. Have had it a few weeks now and continues to function properly unlike similar products. The lock function sometimes seems STP switch on automatically, which I guess is better than the alternative.

We bought this to help control our boxers jumping on people. She is very strong and we have tried many options including positive reinforcement, puppy training, discipline, exercise, and this was a last resort. We have used the sound alert, and the vibration. While we aren't at 100% yet, it is helping her, and us

so far I love it. we have a hound puppy and it has been working great for him

Once we used it once with the beep and then followed by a shock my dog didn’t repeat behavior. Just have to give warning beep. Thank you for a great product

Haven’t used this collar very long yet, but so far it works great.

Too much for my pup, but apart from the static shock feature that I didn't use, everything worked well. I tested it with the tool and that appeared functional, I just never used that part.
