Review on Petrainer PET616A-3 Rechargeable Waterproof Dog Training Collar - Electric Remote Collar with Beep, Vibrate, and Static Modes by Kianoush Hinrichsen

I like everything about this eco-ring except that you can't have different settings for each dog and the shock and vibration intensity is always set the same. I use 99 vibration on my guys to get their attention when they aren't responding. If they ran into the street, I would have to stop and look at the remote control, set the amperage to a lower value, and then shock them. At that point, they could have been hit by a moving car. Vibration on my 8 month old pup does nothing. She didn't care. I'll try to update when she trains more with it. In general, I really like these collars because the battery lasts and the vibrations are strong.
