After emailing the company about my issue, they responded and sent me a replacement. The new unit is noticeably higher quality, with a better power plug port and different looking front.Old review: I was really excited to use this energizer but after 1 month of it barely working it stopped turning on completely. The LED light did turn on when I first plugged it in, but the shock was weak so I thought my problem was the ground. I purchased a 7 foot grounding rod and put it over 4 feet into the ground and attached my ground wire with a grounding clamp. The next time I plugged in the energizer it failed to turn on, no LED light and no shock at all. I emailed the company Agri-Otter but have not received a response yet.I spent hundreds of dollars on accessories like a grounding rod, t-posts, fencing, insulators and wiring just to find out the energizer doesn’t work.
