I have a very annoying barking GSD and i wanted a device that would automatically correct his barking without me having to use a remote. So I bought this.At first, I read the instructions, and it said to test the device by "barking" into the device using your voice. It never worked. But I strapped it onto my dog nonetheless. My dog's barking SOMETIMES triggered this device, and it was never consistent.So I got in touch with the seller and they recommended sending me a different product, I assumed a remote shock collar, which I did not want because it meant I had to manually trigger the device every time my dog barked. I wanted to try the same prduct again because the reviews were so good and I believed I just ended up with a defect.So they sent me another replacement, and this time it was triggered by my voice !!! just as it should. I "barked" into the device, and it triggered the device better (not all the time) than my first one. And it definitely works on my dog.The improvement of my dog is night and day.For users who are wary of shocking their dog, I don't use the shock feature, just beep and vibrate, and it still corrects my GSD. So if you are worried about shock feature, you DO NOT have to use it, which is good since it gives the user an option....

our dogs quit barking right away. just the beep and vibration was enough we didn't need to use the shock mode. they've only had them a week and even with the collars off they have stopped

We have tried 2 other collars. One with a remote, not good because not constant so dog is confused.Another that was not effective.This one works well with very easy to see and change settings.We have lived with her waking us up over a squirrel and everything or everyone she sees move.She learned quickly on low setting.

I recently adopted an 11 year old dog and I was told the previous owner used a bark collar on him. This dog DOES bark a lot--when left alone, when out in the yard, in the car while driving, etc. Some of it was anxiety, which is much better now, but a lot of it is excitement which is fine, but not in your ear. It's been tough to train him because he has a lot of hearing loss. So I got this collar and set it for it's loudest setting for the beep and for vibration--I don't need the shock setting at all! It works like a charm! Since he obviously had previous experience with a bark collar, he knows when this goes on to limit the barking or whining. He can usually get out one bark or low whine and then he stops. He's learning to do all kinds of fun stuff with us now as long as he limits his barking. It's a win win for all of us. It holds it's charge QUITE a long time--we camped for 5 days and he wore it during the days--had plenty of charge left when we got home. It's easy to figure out the settings and the display is clear and easy to read. Easy to charge--just make sure you use the cord that comes with it, it's a little different (longer plug) than a typical micro usb. The only negative I've found is that when he does a big head shake (he's got long floppy ears) I can hear it go off. But since I've only got it set for vibration and tone, that's ok. It will also go off if he's wearing it when sticking his head out window--the sensors are getting pretty windblown--at about 55 mph--makes sense. It's not very frequent either. I would DEFINITELY recommend this, especially using only vibration/tone. :)...

My 2 years old Bella thinks she own the street and no one is allowed to pass by our house not even neighbors dogs are allowed outside lol, it was a big problem for us especially in the summer time where all the fur babies and their parents are often outside, she would bark non stop any time of the day, it was driving us and everyone around us crazy, i said let me try this product give it a try, let me tell u, sometimes if my screen door is open I cannot tell if Bella is inside or outside, it’s a miracle, the instructions says to put it on the dog for at least 12 hours a day which we did, now sometimes I forget to put it on her she still wouldn’t bark, maybe once or twice throughout the entire day, which is not bad at the end of the day it’s ok for her to bark just to let it out she needs to be herself, but nothing like before she actually got used to it and she doesn’t mind wearing it, give it a try u will love this product, I have our setting on vibrate it’s gentle it beeps first then vibrates,...

I like this one, rechargeable with a light to tell you when it's dead or charged，I've had other ones that you had to change the batteries and you don't know it's dead and they are the pricey watch type. I also like that this one gives a warning vibration，he has learned what that means and we don't hear him yelp from being shocked like the other ones. I don't really like the collar, it's just a piece of plastic with holes. which mean it doesn't loosen up, which is good.but you have to hope it's not one hole too tight or next hole too loose. All in all, it's a good value though and we like it....
