Review title: eats batteries
Product review: The collar and unit work well, but as everybody else said, it eats batteries. The company said that having it against metal will diminish battery life, so we got a harness instead (no tags). This still didn't work. We turn it off at night when we take it off. It's too much of a hassle to turn it on only when she is outside. We have gotten to where we let her use it without a battery and she seems to still know the boundaries. Then, we replace the battery to switch it up. Good product, bad battery.
