Even in the woods the given range of these collars is accurate. Less then a week of wearing these collars my 2 yr old lab's obediences has improved 100%. I was hesitant to use the zap to correct them but it only took once. The beep and vibrate work just as well after. And yeah, they love to swim. No doubt the collar is waterproof.

I bought so many cheaper collars. This collar has made it simple to train both my dogs at once. Be careful with shock. I first tested it on myself 16 and it left a mark on my arm. Level 1 works just fine for my dogs level 2 makes them cry. I've only shocked 1 dog once when she went for my neighbors daughter who is scared of dogs. I felt awful

No more barking when im at work they dont know I need to push a button they are good boys when collars are on

Nice product. Once the dog is having the collar, it becomes behaved. The electricity is not necessary as the function of voice and vibration are enough. I want to buy it long time ago, but I was worrying about hurting my dog. However, until a day it bit someone that I made up my mind to buy one, as a half-hundred kg Labrador is not easy to control. The quality of the collar and remote is very good considering the bargain price, I am very happy with how it looks and feels, it also has a nice durable feel to it which is great as it will be able to withstand the daily wear and tear! So far so good, I have no complains!...

The actual collar strap on this is good quality, easy to adjust

Do the job perfectly, just what I expected, safe for my dog Thanks!!
