Review on Lu Ba Rechargeable Vibration Waterproof by Michael Staton

We use these on two of our very active lab dogs. You swim with them in the lake, walk through the mud and fields etc and the collars continue to work well. We're actually on our second set of them. Charging is very easy and takes quite a long time... we charge it every night but never really without power. The remote control is also very easy to use. We highly recommend them. NOTE. We have a dog that is easy to fix with the "Beep" feature. The other is a little more unruly, but the vibrate feature helps with that….
