Review on 🐶 Pedono Waterproof Shock Collar for Dogs - 3 Modes Training with Remote for Small, Medium & Large Breeds by Linda Nelson

I didn't want to buy these but my husband persuaded me. This is a very good training tool. The only thing I don't like is the lack of a "power off" button. I turn the shock in my pocket to zero so I don't accidentally hit him. 1 is the weakest vibration force on impact, 5 is the highest. The sound has only one layer, but that's all it takes. The noise travels quite far, I can hear it from my porch if it's in the back yard. I would suggest adding a switch on the remote that would change the rating to 5 stars.
