Review on Rechargeable Dog Training Collar with Remote - 4 Training Modes, Beep, Vibration, Static Shock - 1000Ft Range - Waterproof & Safe for Large, Medium, Small Dogs - Recording Playback - MODUS Dog Collar by Andrea Smith

I am very satisfied with this shock collar. It seems well made and I love that the remote fits in my pocket. The on/off function on the receiver is also very good. If I want to take it off my dog for a few days, it's good that I can turn it off so I know it's still charged and ready to go when I put it back on, even if I forgot it on the Charger. . The supplied test lamp is also very practical. It's nice to be able to convince yourself that the shock works without having to experience it yourself haha. The light will dimmer or brighten as you adjust the shock level as well, so you can make sure the adjustment is working. The recorded voice commands are amazing too. If my dog is in his kennel when we have company and starts whining, it's a good thing I don't have to go to another room or try to yell all over the house, just push the button and he'll mean it hear command. Very happy with this collar.
