I also thought this charger was fantastic.
Ufortunately it died suddenly in the middle
of my second gardening season. There is no
way to fix it (sealed, no fuses) and it is
just past warranty period. I guess you get
what you pay for...I expect a good quality
charger to last at least 10 years, not just
over one year!

I was in love w/ this charger when I first bought it. It's feels solid, metal construction and MADE IN AMERICA. The gauge was a nice feature most chargers don't have. I thought this charger would surely be the answer to all our fencing needs.

After a few muggy days, I notice that condensation was present in the gauge, but it didn't seem to have an affect on the functionality. I had read several post about the charger, and the moisture in the gauge seems pretty common.

Unfortunately 26 days after purchase, it quit working. We hooked it up to a fully charged marine battery, and the guage would peak out for a minute or two, then it would die... It was so disappointing. Fortunately the feed store I purchased it from gave me a full cash refund.

This charger did not last one year. The box is sealed, so if it blew a fuse, you can't replace it. It worked fine for about 9 months, then one day it just stopped. Troubleshooting was time consuiming, the entire system all works fine--except the charger. This is an expensive item, I would have expected long life--instead I just got taken! Purchase at your own risk!

PROS:
Made in USA
The METER showing it is working
Small size
Strong voltage 'kick'

CONS:
Not 'weather proof'
no 'mounting bracket for metal fence posts'

This 'fencer' has a -healthy- 'shock' that should discourage any animal, even larger ones. It's nice to be able to see how it's working (meter) without having to check it by shorting the fence to ground for a 'spark'.
While it appears to be well made I cannot understand why anyone would make a 'battery operated' fencer that is not weather proof and has no bracket for mounting to a metal fence post - so I am knocking off one star.

I bought 2 of these in the past 2 years. First one failed after 4 months, no user serviceable parts inside, I looked vs. taking a warranty claim. So I bought another one and it lasted 11 months. I like the unit when it works but I would expect this to last 3-5 yrs a minimum for 3 stars, and 5 stars would be a 10yr or longer lifespan. We don't get lightning in my area, just a lot of rain.

Parmak if you are listening - Here is how I would suggest you test these - hook up to a big 12-14V @ 600-700 CCA deep cycle battery and fully short the unit for 6 hrs 2-3 times a day while you cycle it in an environmental chamber from -10F to 120F degrees and vary the humidity from 0 to 95%. If it fails within 3 years redesign whatever failed. Figure out why you are getting warranty returns and address those issues too. Rinse lather repeat until you get it right.

So far so good, hooked it up to a deep cycle battery and was off to the races. This thing does pack a punch compared to the old 110v charger i had. I would strongly recommend putting it in a plastic container like a rubbermaid tub to help keep dust/moisture out.

Cons: These things only appear to work for ~8 years. I've had two of them cr8p out on me at exactly 8 years of age.

Regardless, they work well. The dial tells you when it's time to recharge the battery. If you don't buy this model, make sure and buy another that has a voltage meter on it. The shock it gives is substantial - at least on a quarter-mile line. Not damaging. But it makes you not want to touch it again. Similar to touching a spark plug while it's firing.

We bought this charger to keep bears out of an apiary (bee hives) we started this year. We only have a small area fenced, probably 8 x 6, with three strands of wire. We still haven't needed to recharge the batteries after 6 months of use, and no bear predation! Love it!
