Summary: GREAT PRODUCT
Comment: My neighbors had four dogs that barked every time we went outside. With the dazer they bark no more. This is an awesome product. It also works to help keep our cats off of the table =)
Customer Rating: Summary: It DOES work!
Comment: I was skeptical because I read reviews of other anti-bark products that make "sounds" and the reviews were all over the place. This product does work on our Great Pyrenees, who barks at anything going by the house -- the UPS truck, walkers, the mailman, you name it. We now have to merely pick it up and he stops barking. Interestingly, our other dog is not a barker at all and the sound of the Dazer doesn't appear to bother him at all, which was a real concern. Definitely worth its cost.

Summary: Underpowered?
Comment: The dog dazer doesn't work for me. The concept may have merit, but applications of it are small and inexpensive. I would pay more for a larger version, powerful enough to have an effect.
Customer Rating: Summary: It is working well
Comment: Our neighbor's dogs are reacting to the dazer, I need to click 3 or 4 times when they are barking to stop them.. It seems that younger dogs are more sensitive to dazer, some of them start crying...
The only problem is that you have to be near the barking dogs to stop them.
Customer Rating: Summary: does NOT work
Comment: No matter big or small dog, this product just does not do what it claims. Dogs still bark out loud. This dog dazer II is a waste for me, too bad Amazon lets this be on the market with what I consider, a fake ad. I am back to search for one that really works.
