Gail D 5 out of 512.12.2014 at 9:49 pmRecently purchased this item for my husband for Christmas…of course I had to give it to him early. We have two (2) deer dogs that love running deer so much that they are extremely hard to catch and stop. We tried the system out yesterday and we were completely amazed, it worked great. Definitely will continue to use this product and see additional purchases in our future. Thank you Outdoor Dog Supply!
