Review on 🐶 Wireless Pet Containment System with 1 or 2 Rechargeable Waterproof Shock Collars, Safe Perimeter Electric Dog Fence, Remote Dog Training – No Dig or Underground Wire Fence, from Pet Control HQ by Shelley Highter

So far I've tried it in single mode Very good with single mode collar and remote work I'm going to try duel mode this weekend with my dogs we are currently using Got a little problem installing the railing and I had to ask customer service for help and they had to call me back and go through and help me. Solving the problem made it much easier to understand the process of the fencing and collar remote control duel mode. I must say that their customer service is very good. About remote dueling and fencing I will have to write a review later
