Review on 🐶 Dogtra 3502X Long Range IPX9K Waterproof 1.5-Mile 2-Dog Expandable Dual DIAL Remote Dog Training E-Collar - Ideal for Professional Competition and Working Dog Trainers by David Royles

I was looking for something strong and reliable to train my new GSD puppy. So far this has done exactly what we wanted. Within 24 hours I was teaching her to come to me, sit next to me and walk on a leash. I also bought it to reassure my other dog as she was a bit jealous of her new puppy. It's easy to use with two dogs, the battery life stays full after 3 days of use, very easy to use and you can say you get what you paid for. These collars and transmitters are top notch. Definitely recommend and buy again.
