Review on Bousnic Dog Shock Collar with Remote - Waterproof Electric Training Collar for Small, Medium, and Large Dogs (8-120lbs) - Rechargeable, Beep Vibration, Safe Shock - Control Range 1000FT by David Richardson

I was skeptical but my dog (who is very obedient when within 10 meters of me and less obedient when further away) responded well to this soft reminder collar. I bought this collar to stop a rampaging fence attack when the neighbor's dog was outside. This works great and my dog no longer jumps on the fence and barks frantically when the dog/human/cat/squirrel walks by the house. I believe in this collar. It took about 15 minutes for her to stop her angry barking. Wonderful!
