Review on Flittor Dog Training Collar: Waterproof Shock Collar with Remote for Small, Medium, Large Dogs - 2 Receiver Rechargeable, Beep, Vibration, Shock Modes by Jennifer Verdugo

This is the second set I have ordered. I have FOUR dogs that need "help" to behave or listen to me. I ordered a set to try them out and I liked them so much I ordered another set. The only thing I don't like is that there is only one "pigtail" to charge a collar - two would be better so that both the collars and the remote can be charged together. How I adjusted the collars: A - The most problematic dog is the one that needs the most correction. B - A dog that needs very little correction or will play "deaf" when you need to bring him in from the outside. A/B - When both dogs need to be more careful. A The /B toggle button can be a bit confusing, and even if the collars have been in standby mode for a while, you may need to press the horn button a few times to "wake up" the collar. The beep is loud enough that I can hear it from another room, the vibrations and jolts catching her attention. --Just keep a close eye on which dog you choose, I accidentally clicked on the wrong dog a few times. The discharge setting from 1 to 16 is great, find the lowest that gets your dog's attention. Some setup is required when using the collars for the first time - the user manual explains quite well how to pair each collar with the remote. Overall I like them and the battery life is pretty good.
