This is the second time I bought one of these and it didnt work. Not to mention the screwdriver and batteries had what looked like rust on them. Directions had me looking for adjustment and LED light that don't exist. Others tried and failed to make it work.... Dog is happy with it. Still barking up a storm.
BK208 is the newest anti-bark collar with the most intelligent system.The Bark Control Collar is controlled by a microprocessor which distinguishes your dog’s bark from other environmental noises and automatically delivers ultrasonic and/or static shock after each bark.The collar can effectively and humanely stops barking when it is worn on big dogs.
