We who want to put animals outside and yet want to protect them have a security problem. This product is highly recommended. However, I found these two testimonials so danged funny I'm still chuckling, especially the second one. Cracked me up!! This is the homepage and again, I don't have one and I'm NOT recommending it. However I am considering buying several! http://www.scatmat.com/Products/Scarecrow/?pcontent=overviewpage "I want to let you know that I am very pleased with my new Scarecrow. I was having problems with deer tearing up my garden. I had to replant 3 times and my son found out about the Scarecrow and bought it for my birthday in April. Since receiving it, my garden hasn't been invaded, and all of my plantings are flourishing. We haven't had any rain for the past 3 months and the deer are moving in from the mountains behind our house to forage on green plants. One exception are the quail. They seem to activate the system and parade in front of the sprinkler. Oh well, they are fun to watch and enjoy the shower!!" Roy Fisher Hereford, AZ "My problem has been deer eating my pet petunias. Don’t get me wrong, we love the deer. We just wish they would dine on something other than our roses (and other ornamental greenery). I recently acquired a Scarecrow which I thought would be the answer to my problem. On about the third day in service, I just happened to glance out the window to witness a doe’s first encounter with a Scarecrow. The spigot on the sprinkler head was positioned just right to hit her square in the head from a range of about 12 inches as she moved into the Scarecrow’s field of vision. When a surprising burst of water hit her square in the side of the head at full force, she leapt what I guessed at to be about 8 feet in the air while simultaneously losing control of her personal faculties, and she "hit the road" demonstrating speed that would make Sterling Moss envious. The question is...which is worse? Having your roses pruned, or dealing with the clean-up? In summation, your product works!! My roses no longer disappear when the local deer population come by. This is by far a better solution than shooting these beautiful animals." Brian F. Conrad Victoria, BC
