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!

Ex Output:
positive

I have read all reviews before I bought this, luckily, I received an item with any issue. The stun gun can make loud noisy like other buyers said, the flashlight is not bright enough, but It can blind the attacker. I have try the stun function and my friend said it make a huge painful sense.

Ex Output:
positive

I would give this 5 stars on the product, dropped the rating because of the delivery. I was present when the courier THREW the package out the driver's window onto the driveway vs. exiting the vehicle to place the package close to house. I hope that Amazon or the vendor contact the courier company to lodge a complaint - there is NO EXCUSE for laziness, suppose the product had been fragile? We are on a monthly delivery schedule with this vendor and have been happy until now; hopefully something positive results from this negative posting....

Ex Output:

negative
