"I purchased this to train a Doberman pup. It is pretty good. If there is a lot of noise the beep is so low your dog dont hear it so does not get a warning. Could have a higher beep tone. When the dogs get to playing if caught just right they can turn the switch and turn it off or get it turned to come all the way off. I lost one back in the yard somewhere while they were playing. And there is no replacement for that piece so you have to buy a new one. Wish it were more like the Petsafe battry system where you just replace the whole thing. The range is not what it says. I find that the range I get is about 6 feet not 12. I had one zone that did not work at all when I purchased it. The contacts were so loose the batteries just kind of slopped in it. Overall I would say it was fair. But for the price I expected more from it."
