Review on 🐶 Professional Grade Waterproof Remote Dog Training E-Collar with LED Receiver - Dogtra Edge Long Range High-Output 4-Dog Expandable System (1-Mile Range) by Fatima Garcia

Good trainer! This is probably the only choice if you have 4 dogs (and don't want to flip switches). Other devices have 3 buttons and a switch that needs to be flipped to get to the other dog. The colored lights (for night trips) are AMAZING. There are no questions about where the dog is. I haven't had a chance to test the range of these devices, but even if they only get 1/4 mile (1/4 of the advertised distance) in the woods, that's still 3 football fields away! I'm not sure about the battery life between charges yet, but I'll add a comment to this review later. I wish there was some sort of built in support for the fence. These devices have no sound. Just vibrate, which might be better than the sound. You can't imagine a better arrangement of the buttons/controllers! Not cheap, but very well made! (Devices/receivers also have self-service/replaceable batteries!) PS Unlike Dogtra support, YOU can pair/register multiple collars with one button. (Not something you should do unless you are using the device ONLY for paging/vibrating in special circumstances. You don't want to correct the wrong dog.)
