I like how it can be used when we are away from home, which makes life easier especially if there's no internet access or WiFi/cell service available at our house! Sometimes some of my dogs have issues being in their crates while they sleep due too loud noises (like neighbors cars driving by) but this has not been an issue since installing these headsets because now i know what time zone each dog sleeps so its perfect!! Also sometimes people try coming up out side during training sessions just cause thats where all y'all train around here -_-.
