Review on 🐶 Enhanced PetSpy M686B Shock Collar: Waterproof 2-Dog Trainer with Vibra, Beep & Remote Control by Renee Cook

I have 2 packs, I have 2 aussies who bark all the time and 1 who doesn't come to me when called, he's so bad he just goes limp when I go after him, and everything in itself bites his reach! This collar helps a lot and I only had to use a beep, maximum vibration. That is, IF IT WORKS! The collars will NOT stay on even though they are fully charged! 5 minutes after releasing them I start buzzing on some collar and they don't work. I turn them back on and go about my business until the courier arrives and tries to honk his collar for them to get onto the porch, but nothing happens. Nothing! Then I have to retrieve them and turn them back on even though they are charged! The tines are TOO SHORT, if I had to seriously adjust them they wouldn't feel a thing. Save yourself the headache and buy something else, it doesn't work!
