Bests & Worsts Reviews from Amazon

We've been bothered by a neighbor's dog that comes out periodically day and night and just barks for 10 to 30 minutes -- usually facing our house. We got this product, found a spot in the trees facing the dog, and set it up. It's really worked as advertised. The dog starting barking, as usual, but then seemed to bark fewer times, and with less noise. As three weeks have passed, we hear the dog give one or two "test" yelps (more than barks) presumably to see if it still gets "zapped' by the machine. Since it does, it stops barking immediately. No more gritting teeth (for us) for 10 to 30 minutes, as before. So, I'm delighted with this and wholeheartedly recommend it.
