Rating : - Works on beagles!
I bought this product because the alternative would have ended up with two dead beagles and probably me in jail. Installed it facing over the fence, and the ridiculous howling has been reduced to one howl followed by silence until their little brains forget and they howl again. I'd say the improvement is in the area of 70%, plus the added fact that the owner now sees a flashing light which he thinks is some kind of recording device. I had read that the product does not work on deaf dogs, which may explain the (limited) continued howling. Though expensive, this product is worth a huge amount when compared to the cost of disruption caused by people buying dogs because they think they look cool instead of doing research and realizing that beagles are actually disciples of satan.
