MODUS Ultrasonic Dog Barking Deterrent Device, Anti-Barking Device for Dogs, Bark Control Range of 16.4Ft, Dog Trainer, Wrist Strap, Battery Included, LED Indicate, Indoor and Outdoor

I returned this because it didn’t have any effect on either one of my two dogs. They just continued to bark after I pressed the button.

Useless…zero response from 2 different dogs

Works great , not to big stops my dog from barking immediately. Doesn’t seem to hurt her ears just gets her attention

My walking route takes me along a fenced yard that contains two of the most obnoxious and aggressive yappy dogs that I've ever seen.I tried this device and it had the desired deterrent effect, but only on one of the dogs.My walking route is a loop that I go around several times, so I've had four chances so far to use this device to discourage the aggressive barking. The younger dog quickly learned to keep his distance, but the older dog is not deterred at all. Either he's deaf, he has wax in his ears, or he's just so mean that even the noise emitted by this thing has absolutely no effect. I wish I could find a device with ten times more power to apply even more persuasion to stop the incessant barking.

one thing - over multiple units purchased i have received units with corroding batteries preinstalled. If the manufacturer is not going to use higher quality batteries that do not decay/corrode, maybe they should look at not pre-installing the batteries.otherwise the unit works as advertised with good batteries and the unit is is good working condition.

Works well. I use it to quiet my battling dog when over stimulated by frequent passers by of our apartment.

The package arrived with corroded batteries inside. Had a hard time getting it to work because the battery was stuck. So beware of corrosion when you purchase this irem.

I wasn't sure if this device was going to work, but for the price it was worth trying. It was well packaged with instructions. It also came with batteries, which was nice. I just had to pull the sticker out of the battery compartment, so it would work. There's a light beep I can hear, but it's nothing compared to what my dog hears. I accidentally hit the button when pulling the sticker off the batteries and my dog high-tailed it behind the couch. I was surprised!!! This device is amazing! Since my dog has gotten older, she barks every morning and whines a lot more. She's a 12 year old chihuahua and her hearing is in tact, but she has become complacent and chooses to ignore our commands now. I only use it for barking and whining, but it could be a great training tool for sure. Bonus: My neighbor's little dog is always outside barking non-stop. It goes in and out of the doggy door whenever it pleases. I went outside to try it on their dog and that dog high tailed it into the doggy door! It. Was. Awesome! Now, we can control two dogs with this device. It was worth every penny. I wish I got it sooner....Thank you for making this amazing device.
