Valoin [2019 Newest Dog Anti Bark Collar, 4 Adjustable Sensitivity Levels Rechargeable and Waterproof No Barking Collar for Small Medium Large Dogs

The collar buttons and display seem to work after charging, but it does not make a sound nor vibrate at all, despite my dog's super-loud vocalizations. I tried various settings but still nothing. I am also suspicious of all the five-star reviews for this product. Some reviews describe the product incorrectly (added batteries?) and others seem to be by the same reviewers.

Opened, charged, adjusted, set and put on dog.Yep, that simple. I used the low settings at first...Dog kind of smiled at that. Medium setting worked great.Dog though he was stung by a bee and kept looking for it.Used only a couple of days, and Dog is much quieter. And collar off until Dog forgets.Great value, worked good.

This might work on a dog without much fur but on my part golden it was of no help at all. The pet store told me that on a furry dog these collars won't work unless you shave your dog. That should be stated on the desription.

This has the shock feature which I don't use however my 2 Dachshunds get use to the vibration and sound and will start barking again after awhile.

It turned on, turned off and never came on again. I went to return it and it was 1 day past the return date. Epic fail on this one. Would give zero stars if possible. Should have opened it and tried it sooner.

I have a 10-pound dog and this was a little bigger than i thought but less bulky than the regular bark collars. I would prefer that it would beep at the first bark, vibrate at the second bark and only shock if my dog continued to bark.

Might be user error but we can't get this to work. It did not come with instructions. Any help?

Junk. How do I get my money back after prime 30 days? All lights no sound or shock.
