Works great on training my very crazy 2 dogs very seldom do I have to use the shock usually the vibration is enough and I love you can go stronger or weaker

this arrived promptly and works as expected, only problem is my dog is not scared of the vibration, so to me useless

The material of the control and receivers is high quality. I had no problem setting them up for use and my dogs respond to them. I try to use sound and vibrate, but have not had to raise the "shock" above 2 (it goes to 15). The unit is easy to charge. It is also easy to use both collars at the same time.I would not use the collars as primary collars. They appear to serve more as a way to secure the training receivers around your dog's neck.

So far so good, I have no complains!

I did not hessitate to buy the same collar again.

Only wish I had purchased this ages ago.This no bark collar works great.
