The range for the shock so you can start off very low, and only increase if needed. Very user friendly.

Great for letting my dog run around off leash. I only have to use the vibration mode and my pup comes back to me. :)

Works great. I never need to use the shock feature only vibrate and beep. Dog is doing much better with her training

Like everything about this product. We use it as a last resort to train our dog. It has corrected behaviors in less than two weeks that we've been working on for 4 years.

Battery lasts forever. Range seems fine. Strength is good. We only really use the beep and vibrate modes, so can't say much about the shock function. Overall, great affordable option.

It’s ok
