Review on D.T. Systems H2O ADDON-O Orange Dog Training Receiver Collar by Carrie Johnson

We have two of these for our dogs and they have been great. Fantastic range, this one has a low battery LED indicator which is better than the original we bought. Also, it should be an improvement over the original we have, as the power adjustment is much more gradual and precise. In the original, it sometimes seemed like all or nothing needed fixing, while in this case you can actually tweak it to make the adjustment needed for the situation. The water is impervious to snow and occasional bathing for my dogs.
