I tried it and just sent it back. Reason is that you can't really see (or hear) if it's working and it only works in a radius of about 20 feet. It also irritated one of my babies to the effect that she doesn't want to go out to the back yard anymore. All of the dogs hear the sound if they are barking or not so if you have more than one it is not a good trainings device.
Oh... and if you order it online, even if they tell it is 2 for $10, you are ending up paying $44. I saw it last week at Walmart though for $9.95 (or so) for one... |
