The only repair I’ve had to do on my Premier was this last winter. A rabbit chewed through it. The snow grounded out the netting so it was ineffective. The rabbit did not get shocked. The tracks made it clear what did the chewing. It did not actually chew through the metal wire, just the plastic cord.
Right after I set it up a deer (I assume deer) ran into it and knocked a couple of poles over, but all I had to do was upright it.
My ground is very rocky so I normally use a hammer to install it and drive those prongs in the ground. Sometimes I have to shift around to find a place that is not a big rock so the fence is not always perfectly straight.
