Dog Anti-Bark Collar, Purple, USB Rechargeable

I purchased this but haven't used it, so I'm selling it.

?? Below is the product description from the purchase page!

This is a bark control collar for training dogs not to bark excessively. It automatically switches between beep sounds and vibrations based on the number of times the dog barks.
It is expected to help reduce or stop unnecessary barking.

With each bark, the beep sound duration increases through 7 levels.
Vibrations are added partway through, and the vibration duration also gradually increases.

Additionally, the sensitivity level for detecting barking can be adjusted across 7 levels.
Please use the appropriate level according to your dog's temperament.
Adjust as needed for the situation.
The sensitivity resets to the middle setting each time the power is turned back on.

Rechargeable and reusable - battery lasts 10-14 days.
Charging is complete in 2-3 hours.

- Suitable for dogs with neck sizes from 22 to 55 cm.

Please refrain from using on dogs weighing less than 5kg or younger than 6 months old.

Adjust the belt to fit your dog's size.
