This thing is a life saver. Set up wasn't nearly as bad as I thought it would be. A bit time consuming but not hard.We have it as a back up circling out gates. Between a foster kid and crappy yard people our gate gets left open quite frequently. My Aussie stays or will walk to the front door but my sister's husky will be gone in an instant.The in ground fence helps us keep her safe while we are working on recall and boundary training
