Bests & Worsts Reviews from Amazon

Simple and inexpensive. Works well. Installation tips: Layout the wire where it is to be installed and test this. Next, using a flat-blade spade shovel, have the lead person step on the shovel a couple inches into the ground and pull it back towards them. This creates a wedge opening. The person a few feet behind them tucks the wire in and steps on the ground closing the opening. Easy to install.
