UANAX Ultrasonic Dog Bark Deterrent - Mini Anti-Barking Control Device with 50 FT Range for Dogs - Upgraded Anti-Bark Repellent for Bark Training - Ultrasound Silencer for Dog Security and Anti Bark Solution Review

Don't buy this if you want to stop the dogs barking, it won't do anything. I tried putting it in every position I could think of and it did nothing to stop the dogs from barking. Don't waste money.

Works like a charm! The neighbors bark thoughtlessly like a church mouse since I installed this device in my yard. Highly recommended. Excellent control/behavior modifier.

In 20 degree frost the dogs started barking, checked the battery with a "GOOD" tester. Devise works neither in the test nor in any of the three levels. Brought home after 30 minutes, checked and earned with the same battery. Took it out and came back 1 hour later, same doesn't work!

Bought this item to help my neighbor's dog who won't stop barking. It worked for a few days and now it doesn't work at all and the battery is draining very quickly. I strongly recommend saving money and buying something else. It's not worth $30.
