Rechargeable and waterproof Remote Collar for M556-1/M556-2/M556-3/M613/M623/M633 Dog Training Collar

The product is excellent when used on 1 dog. Dual use is fiddly. Although the after support was excellent and they went out of their way to help I still struggle using it on two dogs at the same time. Every time I set it up it knocks the single dog control off. I maybe doing something wrong but either way I haven’t mastered it. Each dog alone is great and the after service is excellent.
