Waterproof Dog E-Collar Trainer with remote Rechargeable E-Collar for 2 Dogs

I really like this collar. It actually works farther than 2 feet from the dog. I think I've used it about 40-50 feet away. I've only used the beep and vibrate on the collar. My dog responds very quickly and it doesn't hurt him. Since it doesn't need the probes to push onto his neck, it's very comfortable for him and he doesn't mind when he gets it put on in the morning.
