Great product. As much as I dislike squirting citronella up her nose the benefits of keeping Lola under control and safe are fantastic. She is intelligent so now we only have to trigger the the audible warning for her to think about what she is doing. Hopefully we wont even have to do that soon!

I find this item very very good my dog can be a little monster but when he's wearing this collar he's a different dog even when it isn't switched on he can be fooled sometimes just needs it to be switched on just to let him know that it's still works very good

These work great on my 2 100 pound dogs. The remote is very easy to use.

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.
