Review on 🐶 2021 Upgraded BATVOX Bark Collar - Rechargeable, No Shock Dog Barking Collar with Smart Chip, 7 Adjustable Sensitivity Vibration and Sound - Ideal for Small, Medium, and Large Dogs by Chazo Omaha

I ordered these on sale and only had them for 2 weeks, I bought 4, two of the collar clips broke from regular play and I don't expect the other two to last much longer. It's quite difficult to fit a new collar into the little slots in the box unless they're the perfect size, they're smaller, the box itself is bigger than regular collars, and even with the sensitivity settings on their lowest setting cut it off my dogs just shake. or jump around. I don't expect to get them again and wouldn't recommend them to anyone as I now have two that just can't be used.
