Useless

### ⭐⭐⭐⭐⭐ Deer are GONE!
*by S***R on 10 July 2015*

We live in a small community that is plagued by deer. Deer have learned that people will not tolerate the presence of predators (cougars/wolves) in our town, but will accept the risk of road collisions, destroyed gardens and attacks (yes, deer will attack and stomp anything they perceive as a threat, even someone pushing a baby stroller once). A cull is the answer to the lack of predators, but that is politically unacceptable. The misguided believe that the deer were here first and thus they are "natural"; from the perspective of a wildlife biologist I can tell you there is nothing natural about deer with no predation. Thus we have a very large deer population that is uncontrolled. We have planted "deer resistant" plants (they ate them) and even sprayed flowers with a garlic oil mixture (they ate those the next day). Our control was limited to me with a sling shot and this would usually result in a rotation; the one I hit today would not come back for a while, but some other deer would show up to take its place. We would be lucky to go more than two days without deer. I installed the device using the extension cord; ultra-sonic always on and sonic off set to the highest deer setting. PROS: It has been about two weeks since installing the Yard Sentinel and we have not had ONE deer since. CONS: Could be a bit more ruggedly constructed but I'm so pleased that it has worked so well (so far) I'm willing to give it five stars anyway. I will repost should the deer suddenly return and accept that their sudden absence was a coincidence.
