Review on 2800Ft Remote, Rechargeable Dog Training Collar with Shock, Waterproof & Adjustable Levels for Small, Medium, Large Dogs by Molly Hoffman

This large dog shock collar has worked great so far. Not only did I use the beep and vibration, but my dog knows what's coming next from past experiences. This is a good collar and remote control. I like that you have to press the correction button once to change modes and the second does the correction. Helps prevent accidental bumps. Good light function for the night. Easy to turn on and off and good battery life so far compared to what I had before. We are currently working on an off-leash recall and so far so good. Highly recommended.
