Review on Aetertek 919C-1: Advanced 1100-Yard 10-Level 1-Dog Training, Anti-Bark, and Waterproof Collar by Troy Williams

I have changed several collars with my GSD. It's amazing so far! Prior to this purchase he was already trained in a stun collar but this is by far the best collar I have used. It's an anti-bark that you can turn on or off (great feature) since it no longer tears window bars to get to squirrels when we don't have a remote control in hand and it has a remote control to give commands to teach. Beep, shock and vibration options are available. Didn't check the distance. But so far it's been worth every penny!
