Dog training collar 600 yards with waterproof Rechargeable

This collar system works perfectly plus it's so easy to use. I have been using it on our 11 month old lab mix for about 2 months now and he has improved overall so much from his pulling on walks, taking food from kitchen counter, and not running away if he gets out of our fenced yard. He's only been shocked a few times on 2 or 3 and now I usually only use the tone and he stops his bad behavior immediately. Still need to work more on his barking though. Plus I'll be using the 2nd collar on our 5 month old border collie soon for her digging habits and rough playing with our lab mix. Quality product for a VERY good price!
