Bests & Worsts Reviews from Amazon

Very easy to setup and easy to understand. My pet was trained almost immediately upon his first jolt. This is probably because of the shock setting; even at its lowest setting will give your dog enough of a jolt to make him yelp and hide with his tail between his legs. I should include that maybe this will only do that to dogs under 50lbs, maybe. Each dog is different, maybe your dog is into that kind of thing and will want a higher jolt. Either way, it worked well enough for my dog that he no longer needs the collar around the backyard. Before you think I'm some jerk for putting my dog through that without testing or training him first... I DID test it and train him with just the beeps, but he didn't really care until I actually turned it on to shock him. I also tested all 5 shock settings on myself prior to putting it on him. I too no longer want to leave my backyard.
