These aren’t cheap, but my old one lasted about 5 years. They are powered by a small battery and charged up by solar. I have maybe 500 feet or so of paddock electrified so horses won’t chew on cross rails. After buying the new one I found a YouTube vid explains how to take old one apart to get at the battery. Bought a battery fro something like $35. Took old one apart, charged and installed new battery, put back together and works fine. Not hard to do if your a little bit handy. Installed the new one & have a backup. By the way, this is outside 24/7 in northern Ohio mounted on the barn wall facing south. Not covered and very exposed to elements. Hard to believe that old battery lasted so long (5-6 years) in those extreme conditions. Here it can get below zero and tons of snow in winter & blazing hot in summer. Good product & easy to install.

Like this charger a lot , easy to setup, does what it supposed todo. I was surprised at the jolt that it dished out , won’t test it again. Its on 24/7, day/night, keeps the horses where they belong, keeps the wildlife from getting into the duck yard. It’s still doing it’s job well with less sunlight. It was well worth buying .

My mare, Cassie, is a challenging creature. She is equal parts beauty and brains, and therefore, she likes to test the capabilities of the electric fence. There isn't a creature alive that could complete such thorough R&D on a fence, so it is of the utmost importance that my fence is functional. My previous fence charger took its last breath at the very worst time. My husband was out of town for work and I (a 125 pound woman) had to fix it on my own, and quickly. I am not skilled with this sort of thing. I can build a wooden fence well enough. But at the time of install, it was 100 degrees outside and I am a disabled duck who gets dizzy from the mere act of standing under the hot, summer sun. I ordered this bad boy and set about installing it. To my surprise, it was as easy as pie. Took me a grand total of 20 minutes to install it, check my ground wire, and check to ensure the voltage was indeed appropriate. I let it charge for a full day and it has been smooth sailing ever since. If this one ever stops working I'll probably buy two more simply for how easy it was for me to set it up.

I set up the whole solar electric fencer as per instructions over a 2 km stretch With 100% success. Easy instructions to follow and sturdy parts.

So far very impressed. Shock was a little lighter than I expected but it’s enough to send my pigs squealing which was it’s intended purpose. Have not been without sun for more than a day but it seems to keep working as intended.
