Hazie A006 [Upgraded 2018] Bark Collar with New Chip 7 Levels Button Adjustable Sensitivity Control, Stimulation of No Harm Warning Beep and Vibration, for 15 to 120 Pounds Dogs

When I purchased this I thought the +/- was for strength of the shock. It’s not, it’s for the sensitivity of the bark sensor. I’m not sure why some people’s arent powerful enough. The collar works in stages. The first stage is a sound warning, then each time it goes off the shock increases in strength. Before I put this on my dog I tried it on myself. Let me tell you when it gets to the 4 level of shock, it is way too powerful for a small dog. I’d never leave this on my dog. If it had some way to reduce the shock it would be a good product.

I bought this as a Secret Santa for my neighbor. At first I wasn't sure if they would even use it but after a week or two I noticed the lack of barking on the other side of my fence. Merry Christmas to me. Its been almost 6 months and the dog is still wearing it and still not barking.

Does it's job. Battery won't last too long. Maybe 2 weeks

This is the absolute worst product. I wish I could link a video of my dog who is currently barking and the collar isn’t doing anything. Do not waist your money because this procduct is a joke. It goes off when he scratched but not when her barks.

These are horrible! My dog is currently outside barking like crazy. The strap doesn’t stay tight. I have to remove and tighten all day long. When my dog shakes I‎t triggers I‎t and I‎t will beep however when she barks nothing happens. Sending back and getting something better.

It has a lot of warning beeps

The damn thing doesn't stay tight and randomly beeps and shocks my dog when she isn't barking or anything at all.

Didn’t even last 3 months
