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

My dog is a runner... It works great. Stops him right in his tracks!

This has been a great product for the price.

I got this for my 7 month old puppy. She has been biting at my son and barking at neighbors. This helped make her listen better and stop.
