Query: Amazing!!

The best $300 I have ever spent!!! Set up was extrememly easy. My dog learned very quickly where he was allowed to go without getting a beep or zap. I have never used this on a setting higher than the lowest zap and he responds immediately to the beep. Also, for those who feel bad about zapping their dog. My roommate and I both tried it on ourselves and it took both of us a minute to realize it was even shocking us! If you asked my dog, he would say it lit his butt up. LOL Very Very Satisfied with my purchase and would definitely recommend this product to anyone having problems with keeping their dog in the yard!
