Although I don't doubt that the product works to quiet dogs, the design is extremely feeble and it is difficult to use. I agree with other users on the fact that an ON/OFF switch added to the timer would be a much smarter approach to using the product. Although it is possible to find tricks to turn on the product (for example, setting the timer ON a couple of minutes after the current real time) it would be much easier to simply have a switch. As far as the barking goes, the dogs next door are indeed quieter since I started using the product. However, they still bark a little bit. I think a newer generation of this device, with a better, stronger design; an ON/OFF switch; a real weather-proof digital display (I have used the product for less than three weeks and the display is already a bit fuzzy!); as well as better ultrasonic speakers (to really quiet dogs down!) would greatly improve what today I see as a SOMEWHAT MEDIOCRE PRODUCT.Get more detail about Lentek Super Bark Free Pro Series Dog Training Device.
