The only e-collar we’ll ever use! We were VERY picky when choosing a collar for off leash training/recall. (linked some of Shadow’s fav treats too!) Great range. Easy to use. Love the vibration + stimulation features. Waterproof! And at night, we turn on Shadow’s “headlights” so we can see her in the dark. 10/10 recommend LTKfamily LTKtravel
