Q: Now we are living a bark free life! Within two days it had cut out 99% of non-essential barking! At last you can feel peace and quietness in our house! We love our beagles but they were driving us crazy! It really detects barking from far away, now we don’t even hear our neighbor dogs. Great quality and cute btw...This has been a life saver! We are able to get proper sleep now!

A: positive
