So far I am very happy with this purchase.

Works well. Good strength. Vibration setting works well with my dog.

Amazing. Works great. Better than the rest by far. Durable and reliable.

This worked great for my dog. We have a 6 month old cattle dog and she responded great to this. She returns to our house quickly when using the beep function. I would definitely recommend this for anyone struggling to help train a dog with basic daily functions.

Seems well made. Looking forward to continuing to train our dog.

This product is excellent. After receiving it and using it for a couple of weeks, I am so impressed. Very surprised the cost is not much more ! After just 2 weeks all we have to use is the vibration button.
